The document discusses best practices for writing clean JavaScript code, including avoiding global variables, properly encapsulating variables, and batching DOM operations for performance. It emphasizes using strict comparisons, templating frameworks to help avoid common pitfalls, and following principles like KISS and SRP. Overall it stresses the importance of coding discipline, iterative development, and expressing code in an unambiguous way to facilitate collaboration.
The document discusses recursive functions in programming. A recursive function is one that calls itself during execution. The key aspects are that recursive functions must have a condition to control how many times the function calls itself to avoid infinite recursion, similar to a loop condition. The document provides examples of a simple recursive message printing function that calls itself a specified number of times determined by a parameter passed to the function.
Basic introduction to pure functions using Javascript as the language. Introduction to some concepts as side effects, referential transparency and shared state.
The document discusses the Struts framework and the Tiles plugin. It provides an overview of Struts, describing its main objects and MVC architecture. It then explains what a plugin is and how it can be used to extend Struts functionality. Specifically, it details how the Tiles plugin addresses limitations of including layouts across pages by defining templates that can be reused. It provides an example of configuring and using the Tiles plugin with Struts to define page layouts, headers, footers and dynamic content in a modular way.

9. A book shopping cart application demonstrating various concepts
10. A case study on building an employee or book management system with MVC,
Every bit of JavaScript code runs inside an Execution Context. This key principle is the base of the closures. Mastering closures is key when writing JS code and apps.
JavaScript global object, execution contexts & closuresHDR1001
The document discusses key JavaScript concepts including the global object, execution contexts, closures, and 'this'. It summarizes an article explaining that the global object exists as a single copy accessible anywhere and ends with the program. Execution contexts contain variable objects and have a stack structure. Closures occur when a nested function references variables in its parent function's scope. The value of 'this' depends on how a function is called. Diagrams are included to help illustrate these concepts.

This document provides an overview of object-oriented concepts in JavaScript. It defines JavaScript and its components like ECMAScript, DOM, and BOM. It discusses how JavaScript supports object-oriented programming features like polymorphism and inheritance through prototypal inheritance despite not being a classical OOP language. The document also covers JavaScript data types, objects, scope, closures, context, and methods for changing contexts like call and apply.
The document discusses user defined functions (UDF), views, and indexing in SQL Server. It provides an example of a UDF that returns a teacher's name based on their ID. Key differences between stored procedures and UDFs are that UDFs are compiled at runtime, can't perform DML operations, and must return a value. Views are described as customized representations of data from tables that don't take up storage space themselves. Indexing improves the speed of operations by organizing data to allow faster searches.
The document discusses different programming paradigms including imperative, object-oriented, functional, protocol-oriented, and functional reactive programming. It provides examples of code using each paradigm and how to recognize them. It notes that the paradigms often mix together and provides some additional resources on concepts like monads, signals, and bridging between paradigms in Swift.
Over recent years, JavaScript has increasingly gained popularity, partly due to libraries that are developed to make JavaScript apps/effects easier to create for those who may not have fully grasped the core language yet.
While in the past it was a common argument that JavaScript was a basic language and was very ‘slap dash’ with no real foundation; this is no longer the case, especially with the introduction of high scale web applications and ‘adaptations’ such as JSON (JavaScript Object Notation).
The document discusses several principles of object-oriented programming including:
1. The Single Responsibility Principle which states that classes should have single responsibilities and separates the logging functionality.
2. The Open Closed Principle which makes classes open for extension but closed for modification through inheritance.
3. The Liskov Substitution Principle allows subclasses to behave in the same way as the parent class.
4. The Interface Segregation Principle splits interfaces that are very large into smaller and more specific ones for easier implementation.
5. The Dependency Inversion Principle states that high-level modules should not depend on low-level modules but both should depend on abstractions. This allows for looser coupling
This document discusses JavaScript control statements including for loops, switch statements, do-while loops, break and continue statements, and logical operators. It covers the basic syntax and flow of each statement type with examples. Key topics are counter-controlled repetition with for loops, using break and continue to control loop execution, and applying logical operators like AND, OR, and NOT in conditional statements.

RxJava makes dealing with concurrency and asynchronous operations easier by allowing data streams to be combined, transformed, filtered and mapped. It encourages defensive programming and simplifies error handling. RxJava represents asynchronous data streams and allows these streams to be composed through the use of operators. Observables emit items to observers, and operators allow transforming the streams by mapping, filtering, debouncing etc. This introduces a more functional reactive approach to programming with asynchronous data.
This document discusses object-oriented programming in JavaScript. It covers built-in objects like Object, Function, and Array. It also discusses creating custom objects using constructor functions and prototypes. Constructor functions allow initializing object state, while prototypes allow defining shared object behavior. JavaScript uses prototypal inheritance, where an object inherits directly from another object instance.
A low Overhead Per Object Write Barrier for SmalltalkESUG
This document describes a new feature for the CogVM that allows any object to be marked as read-only. It introduces APIs to mark objects as read-only or writable. When attempting to modify a read-only object, it will fail and trigger a callback. The implementation details are discussed, focusing on how to keep instance variable stores efficient by checking for read-only objects in the generated x86 machine code. Evaluation shows the overhead is minimal for most use cases, up to 17% slower in pathological cases, but has since been optimized.
EJB 3.1 allows developers to create enterprise Java beans as simple POJOs annotated with EJB annotations rather than extending framework classes. It supports stateless, stateful, and singleton session beans that can be injected into other beans and exposed as RESTful web services. New features include annotations for singleton beans, startup beans, timers, and exposing beans through REST. EJBs can be easily unit tested outside of the container using an EJBContainer.
This document provides an overview of the history and evolution of JavaScript. It discusses key dates and specifications including its first appearance in 1995 in Netscape Navigator 2.0 and the standardization process in the late 1990s. The document also covers JavaScript's core features like being dynamic, single-threaded, asynchronous and event-driven. It describes JavaScript's data types, objects, functions and common array methods. Overall, the document presents a comprehensive introduction to JavaScript from its origins to modern usage.
This document provides an overview of advanced JavaScript concepts beyond jQuery, including traversing the DOM, element objects, functions, native objects, closures, manipulating data with array methods, prototypal inheritance, revealing modules, and function composition. It discusses using vanilla JavaScript instead of jQuery for DOM manipulation and events. It also explains JavaScript functions, closures, and how functions are first-class citizens that can be assigned to variables and passed as arguments. The document outlines prototypal inheritance in JavaScript and alternative patterns like factories and composition. It provides examples for working with arrays, closures, and building reusable objects.
React js use contexts and useContext hookPiyush Jamwal
The document discusses the useContext hook in React. It explains that hooks are special functions that start with "use" and are analogous to class component methods. The useContext hook allows components to access data from their parent context without having to pass props down through each level. Without useContext, data would need to be passed through props from the parent component to child components. With useContext, a Context Provider wraps components and provides a value that can be accessed using useContext in any child component without passing props.
This document discusses the keyword "this" in JavaScript and how its value is determined. It provides examples of how "this" refers to the global window object, a calling object, or can be undefined. It also demonstrates how "this" refers to a DOM element when used in an event handler. The document concludes that "this" generally refers to the global context, but can refer to a new object when used with "new" or a member object when called as a method, unless asynchronous.
This document discusses options for using Django with MongoDB, including object-document mappers like MongoEngine and Mongokit. It notes that some Django contrib apps may be broken but the admin will work. Benefits highlighted include reduced impedance mismatch, support for new fields like aggregations, gridfs, caching, map reduce, and indexes. Suggestions include using raw queries, embedding documents when possible, rethinking models, only using MongoDB for certain apps/models, serving static files via GridFS, and leveraging aggregations and map/reduce. It warns against migrating data and notes dates work but month/day queries do not.
This document summarizes JavaScript functions and patterns. It covers function application using call and apply, functions as first-class objects with local scope, different ways to declare functions like expressions and constructors. It also discusses named vs anonymous functions, function hoisting, functions as callbacks, returning and redefining functions, immediate functions, and memoization.
Introduction to Object Oriented Javascriptnodeninjas
This document provides an introduction to object oriented JavaScript. It covers functions, objects, prototypes, inheritance, callbacks, closures, asynchronous programming and some exercises. Functions are first class citizens that can be treated like variables. Objects can be created using constructors, literals or built-in methods. Prototypes allow objects to inherit properties from other objects in a prototypical inheritance chain. Callbacks and closures help deal with JavaScript's asynchronous nature. Asynchronous flow control with promises avoids "callback hell". Examples are provided for key concepts.
This document discusses object-oriented programming (OOP) principles and functional programming (FP) concepts. It covers SOLID principles like single responsibility, open/closed principles and dependency inversion. It also discusses design patterns like command and observer patterns and how they can be expressed functionally using higher-order functions. The document notes that popular programming languages have evolved from a multiparadigm approach in the 1980s to an object-oriented dominance period, and are now becoming increasingly multiparadigm again with integrated support for functional programming concepts.

Object-Oriented Programming has well established design principles, such as SOLID. For many developers architecture and functional programming are at odds with each other: they don’t know how their existing tricks of the trade convert into functional design. This problem becomes worse as hybrid languages such as Java 8 or Scala become common. We’ll talk about how functional programming helps you implement the SOLID principles, and how a functional mindset can actually help you achieve cleaner and simpler OO design.

This document discusses different approaches for creating objects in PHP, including using static factory methods instead of constructors, enforcing singletons, making classes non-instantiable, and using the builder pattern. For static factory methods, the pros are that they are clearer and avoid ambiguous constructor parameters, while the con is they are harder to chain for subclasses. Singletons are efficient but can introduce state issues. Making a class non-instantiable clearly communicates its usage. The builder pattern prevents malformed objects and provides a nice chained interface, but is more complex.

We often come across the term "Design Patterns" but some of us might be interested to know what they truly are. Its necessary to know the value and benefits design patterns bring to the software development process, mostly in the areas of maintenance and code reuse.
This document discusses several JavaScript design patterns including singleton, module, engine, event-driven programming, and templates. It provides code examples and explanations for each pattern. The patterns are introduced as ways to make programming easier by improving code organization, reuse, separation of concerns, and error handling.
The document discusses Django, a Python web framework. It began as an internal project at a newspaper to help journalists meet deadlines. Django encourages rapid development, clean design and is database and platform neutral. It features an object relational mapper, automatic admin interface, elegant URLs and templates. Django uses a model-template-view architecture. It provides tools like manage.py to help with development.
SOLID
From Wikipedia, the free encyclopedia
===============================
SOLID Principles :
Single responsibility
Open/closed
Liskov substitution
Interface segregation
Dependency inversion
In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable.
Three Simple Chords of Alternative PageObjects and Hardcore of LoadableCompon...Iakiv Kramarenko
Three simple approaches for implementing web UI automation were discussed: PageObjects, LoadableComponents, and PageUtils. PageObjects use object-oriented inheritance but can become complex. LoadableComponents encapsulate page loading logic but may lead to overcomplicated hierarchies. PageUtils use a procedural approach with functions to represent pages and elements, avoiding complexity while enabling easy tests. Functional programming concepts like higher-order functions can help address lack of DRYness in the procedural approach. The best approach depends on the project needs in terms of teaching others, speed of development, and ability to handle future changes.
Presented at jDD Krakow Oct 2017
Developers love to complain about their legacy systems, but if you have a legacy system, it means you have a working, successful system which deliver real value to business, and this is definitely a good thing.
This document discusses principles for writing clean code in functions. It recommends that functions should be small, do one thing, have descriptive names, and avoid side effects. Functions with many arguments or switch statements are harder to understand. Exceptions should be used instead of return codes to indicate errors. Overall, following best practices for functions helps produce code that is easy to read and maintain.
The document provides an overview of JavaScript design patterns including creational, structural, and behavioral patterns. It discusses common patterns like the module pattern, prototype pattern, factory pattern, decorator pattern, observer pattern, and more. Code examples are provided to demonstrate how each pattern works in JavaScript.
Esta charla comprende las lecciones aprendidas convirtiendo la app de Android de Teambox (una app repleta de deuda técnica y con un alto nivel de acoplamiento entre clases), en la versión actual de Redbooth, que intenta cumplir la arquitectura Hexagonal y los principios SOLID. Durante la exposición explicaremos como fuimos desenredando el código paso a paso; como aplicamos por partes los conceptos de la arquitectura hexagonal; como dejamos de lado componentes del framework de Android que dificultaban el mantenimiento de la app; y que errores cometimos, como los solucionamos y como se podrían haber evitado.
JavaScript is the programming language of the web. It can dynamically manipulate HTML content by changing element properties like innerHTML. Functions allow JavaScript code to run in response to events like button clicks or timeouts. JavaScript uses objects and prototypes to define reusable behaviors and properties for objects. It is an important language for web developers to learn alongside HTML and CSS.
Asynchronous single page applications without a line of HTML or Javascript, o...Robert Schadek
AngularJS, together with Node.js, is an extremely powerful combination for building single page applications. Unfortunately, its development requires writing HTML and Javascript, which is tedious and error prone. By using vibe.d, HTML is no longer necessary, and the developers can use the full power of a static-typed language for the development of the backend. Substituting Javascript with Typescript in addition to a little bit of CTFE D magic then removes the need for redundant data type declarations, and makes everything statically typed. At the end of the talk, the attendee will have witnessed the creation of a statically typed, asynchronous single page application that required little extra typing than its dynamically typed equivalent. Additionally, the attendees will be motivated to explore the presented combination of frameworks as a viable desktop application UI framework.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

3. Case study
Class Book {
Function getTitle() ;
Function getAuthor() ;
Function turnPage() ;
Function printCurrentPage (String printerType) :
Switch (printerType) :
Case “plainTextPrinter” :
return “plain text printout” ;
Case “htmlPrinter” :
return “html printout" ;
Function savePage(String persistenceType) ;
Switch (persistenceType) :
Case “flatFile” :
return “save page in flat file” ;
Case “mysql” :
return “save page in mysql DB” ;
}
5. Wrong! why?
Class Book {
Function getTitle() ;
Function getAuthor() ;
Function turnPage() ;
Function printCurrentPage (String printerType) :
Switch (printerType) :
Case “plainTextPrinter” :
return “plain text print out” ;
Case “htmlPrinter” :
return “html print out" ;
Case “xmlPrinter” :
Return “xml print out” ;
Function savePage (String persistenceType) :
Switch (persistenceType) :
Case “flatFile” :
return “save in flat file” ;
Case “mysql” :
return “save in mysql DB” ;
}
6. Why these solid principles?
● System Maintainability
● Changes always happen
● Reduce time to add feature/fix bug
● Easier for other engineers or ‘a future you’ to quickly understand the
codebase
7. Solid Principles
S - single responsibility principle
O - open/closed principle
L - liskov substitution principle
I - interface segregation principle
D - dependency inversion principle
8. Solid Principles: Single Responsibility Principle
● Your class should have just one reason to change
● Look for actors in your system
● An actor should have a single job description
● Don’t be confused with a single person acting multiple roles
● Create a class/module for each actor
9. Solid Principles: Single Responsibility Principle
● Three actors
○ Book Reader
○ Printer Man
○ Records Man
10. Solid Principles: Single Responsibility Principle
Class Book {
Function getTitle() ;
Function getAuthor() ;
Function turnPage() ;
Function getCurrentPage() ;
Function getNextPage() ;
}
Class Database {
Function saveBook(String databaseType) ;
Switch (databaseType) :
Case “flatFile” :
return “save in flat file” ;
Case “mysql” :
return “save in mysql DB” ;
}
Class Printer {
Function printBookPage (String printerType) :
Switch (printerType) :
Case “plainTextPrinter” :
return “plain text printout” ;
Case “htmlPrinter” :
return “html printout" ;
}
11. Solid Principles: Open/Closed Principle
● Classes should be open to extension but closed to modifications
● Do not modify classes to add a type of actor in your system
12. Solid Principles: Open/Closed Principle
Printer Class Case Study:
Class Printer {
Function printBookPage (Printer printer) :
printer.print() ;
}
Interface PrinterInterface {
print() ;
}
Class HtmlPrinter implements PrinterInterface {
Function print() :
return “html print out” ;
}
Class PlainTextPrinter implements PrinterInterface {
Function print() :
return “plain text print out” ;
}
14. Solid Principles: Liskov Substitution Principle
● Subclasses can substitute parent classes without breaking functionality
(or changing behaviour)
○ New exceptions shouldn’t be thrown in the derived classes
○ Pre conditions cannot be strengthened in the derived classes : integer only
negative example
○ Post conditions cannot be weakened : DB open/close example
15. Solid Principles: Liskov Substitution Principle
Class Printer {
Function printBookPage (PrinterInterface printer) :
printer.print() ;
}
Interface PrinterInterface {
print() ;
}
Class HtmlPrinter implements PrinterInterface {
Function print() :
return “html print out” ;
}
Class BrowserPrinter extends HtmlPrinter {
Function print() :
If (internet explorer) {
Throw IHateInternetExplorerException();
}
return “print browser page” ;
}
16. Solid Principles: Interface Segregation Principle
● Interface should represent one discrete cohesive behaviour
● All methods in an interface should be implemented
17. Solid Principles: Interface Segregation Principle
Interface PrinterInterface {
print() ;
removeInk();
}
Class POSPrinter implements PrinterInterface {
Function print() :
return “POS print out” ;
Function removeInk()
Throw new doesNotHaveInkException;
}
Interface InkableInterface() {
Function removeInk();
}
18. Solid Principles: Dependency Inversion Principle
● A high level module should not depend on a low level module, both should
depend on abstractions
● Abstractions should never depend upon details, details should depend upon
abstractions
