This document discusses functions in JavaScript. It defines a function as a block of code that performs a task and can be called multiple times. Functions are first-class objects that can be passed as arguments to other functions, returned from functions, and assigned to variables or object properties. Functions provide their own execution context and scope their variables to the function body. Functions are defined either with a function expression or function declaration and are called directly by name or indirectly via methods like call, apply, setTimeout. The value of the this keyword inside a function depends on how the function is called and refers to the execution context object.
The document discusses various ways to manage undo space in an Oracle database including manual and automatic undo management. It provides SQL commands for configuring undo management and calculating the optimal undo retention parameter and undo tablespace size.
The document discusses friend functions and classes, which can access private and protected members of another class. It provides examples of declaring friend functions and classes, and demonstrates how friend functions can modify private variables, while non-friend functions cannot. The document also covers static class members, which are shared by all objects of a class, and proxy classes, which hide the implementation of another class through a public interface.
Constructors and destructors are special member functions in C++. Constructors initialize objects and are invoked when objects are created. There are three types of constructors: default, parameterized, and copy constructors. Destructors destroy objects and are used to perform cleanup when objects go out of scope. Constructors do not have a return type while destructors are declared with a tilde symbol preceding the class name but do not have arguments or return values.
The document describes an algorithm used to purge data from a large IBM DB2 database to reduce its size. Key steps included:

The document discusses class objects, constructors, and destructors in C++. It provides an example book class with private data members and public member functions to manipulate the data. Constructors allow objects to initialize their data automatically upon creation without requiring separate calls. Destructors perform cleanup tasks when objects are destroyed. The document also demonstrates how objects are defined and member functions called, and provides examples of classes with constructors and destructors.
1. Constructors are special member functions used to initialize objects. They are called whenever an object is created and have the same name as the class.
2. Constructors can be default, parameterized, overloaded, or have default arguments. The default constructor takes no arguments.
3. A destructor is a special function that is called when an object is destroyed. It performs cleanup tasks like closing files. It has the same name as the class but preceded by a tilde (~).
The document provides specifications for a regular expression problem involving matching words from a dictionary to tile patterns containing wildcards. It specifies that the system should:
1) Find words from the dictionary that match patterns formed by 7 tiles, where blank tiles act as wildcards.
2) Perform the matching in O(n) time complexity to allow processing hundreds of tile sets efficiently.
3) Include test code that verifies the solution by exhaustively generating all permutations of tile patterns and matching them to words, for comparison with the algorithm's results.
This document discusses best practices for handling null values in Java. It recommends: failing fast with NullPointerExceptions instead of silently returning null; never returning null values from methods; marking optional parameters and return values with Java's Optional class; using Optional's map and flatMap methods to avoid deep null checks; and using Guava transforms if on Java 6/7 prior to Java 8 streams. The document provides code examples demonstrating these techniques for optional user objects returned from databases and assigned to groups.
The document discusses handling XML data in databases using the SQLXML interface in Java. It introduces the SQLXML interface that allows storing and retrieving XML data from databases. It provides code snippets that show how to:
1) Create an SQLXML object and insert an XML document into a database table
2) Retrieve an XML document from a database table using an SQLXML object
3) Update an existing SQLXML object in the database
This document discusses lexical environments and execution contexts in ECMAScript according to ECMA-262 Edition 5. It explains how lexical environments contain environment records that bind identifiers to values and reference outer environments. Execution contexts contain a lexical environment, variable environment, and this binding. The document provides examples of identifier resolution, function closures, and how the with statement affects lexical and variable environments.
constructor with default arguments and dynamic initialization of objectsKanhaiya Saxena
This document discusses constructors and dynamic initialization of objects in C++. It defines a constructor as a member function with the same name as the class that is used to create and initialize objects. A default constructor is one that has no parameters or all parameters have default values. Dynamic initialization allows initializing class objects at runtime by providing values during program execution rather than at compile time. An example demonstrates defining a class with different constructors and dynamically initializing an object by passing user input to a constructor that calculates and displays the sum.

There are three types of constructors: default, parameterized, and copy. The default constructor takes no arguments, parameterized constructors allow passing values during object creation, and copy constructors copy the values of one object into a new object. Destructors are special member functions that destroy objects and are declared with a tilde symbol preceding the class name. They are called automatically when program execution finishes or an object is deleted.

Monadic Comprehensions and Functional Composition with Query ExpressionsChris Eargle
Build monads using the C# language with a C# style, then use the appropriate methods to ensure the LINQ query syntax works with this functional design pattern. After describing monads, we will cut the middleman and apply the same techniques directly to objects and functions to achieve better results with a declarative syntax.
This document provides an overview of new features introduced in ECMAScript 6 (ES6), including arrow functions, constants and let declarations, template literals, classes, modules, promises, symbols, and more. It explains these features through examples and comparisons to ES5. Key points covered include arrow function syntax, block vs expression bodies, let and const block scoping, default parameters, destructuring, rest and spread operators, tagged template literals, class syntax and inheritance, module imports and exports, symbol use cases for unique keys and constants, and for...of loop iteration vs for...in enumeration.
The document defines a LineChart class that extends the Chart class. The LineChart class constructor calls the parent constructor and draws the chart. The draw method builds a line chart from the series data using an SVG library, appends it to the canvas, and adds statistics for each data point by calling the parent addStats method. The getSerieData static method calculates max and average values for a data series. The class is exported for use in other code.

Principles of functional progrmming in scalaehsoon
a short outline on necessity of functional programming and principles of functional programming in Scala.
In the article some keyword are used but not explained (to keep the article short and simple), the interested reader can look them up in internet.
This document summarizes a presentation on Scala given by Jonas Boner. It shows how to build a simple chat application in 30 lines of code using Lift framework. It then discusses Scala as a scalable, pragmatic language that blends object-oriented and functional programming. Traits allow for rich and extensible abstractions. Pattern matching, immutable data structures, and functions as first-class values enable a functional style. Tools like SBT and frameworks like Lift make Scala productive for real-world use.
Short (45 min) version of my 'Pragmatic Real-World Scala' talk. Discussing patterns and idioms discovered during 1.5 years of building a production system for finance; portfolio management and simulation.
This document summarizes advanced JavaScript concepts including:
- Object-oriented inheritance patterns in JavaScript and trends toward avoiding new and emulating private members. Pseudo-classical inheritance is recommended for better performance.
- Exploiting JavaScript's support for functional programming with higher-order functions to allow functions as arguments and return values for more flexible programming.
- Common issues with asynchronous code in JavaScript and how promises can help address callbacks and synchronization.
- Common pitfalls to avoid with arrays, numbers, and typeof in JavaScript.
The document provides an overview of several C++ concepts including basic syntax, compiling programs, argument passing, dynamic memory allocation, and object-oriented programming. It demonstrates simple C++ programs and functions. It discusses best practices like separating interface and implementation using header files. It also introduces C++ standard library features like vectors and the importance of avoiding unnecessary copying.
ES7 introduced the exponentiation operator (**) and Array.prototype.includes() method. ES8 introduced async functions which allow asynchronous code to be written in a cleaner way using async and await keywords, shared memory and atomics to improve parallelism and concurrency between workers, and new methods like Object.entries() and Object.values(). Current proposals for ES9 include object destructuring with rest and spread properties, async iteration with for-await loops, and dynamic import() to load modules at runtime.
C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.
This reference will take you through simple and practical approach while learning C++ Programming language.
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.
This document provides an overview of React.js and key concepts like components, props, state, and JSX syntax. It also discusses performance techniques like virtual DOM and how React efficiently re-renders. Additionally, it covers related topics like Redux for state management and separating concerns with a component architecture.
This document discusses first-class functions and lambda calculus. It begins with an overview of Alonzo Church and the origins of lambda calculus. It then covers first-class functions in JavaScript, functions as objects in Java, and first-class functions in Scala. The document also discusses generic higher-order functions and control abstraction.
Generators in ECMAScript provide a way to write iterator functions using the yield keyword. This allows for writing functions that can be iterated over manually or used to create infinite streams. Generators also enable asynchronous programming using coroutines instead of callbacks. They allow for cooperative multitasking by starting multiple generator functions as "threads" that yield values in a nondeterministic order. Array comprehensions are also proposed as a shorthand for transforming arrays using generators.
This document summarizes new features introduced in ES2015 (ES6), including let and const block scoping, arrow functions, template literals, destructuring, classes, modules, and methods added to built-in objects like String, Array, Number, Math and more. It recommends using features like let, const, arrow functions, and template literals that improve code clarity and syntax, while being cautious of less supported features like iterators, generators and proxies that may require polyfills or have limited browser support. The document provides examples and explanations of many ES6 features and references additional learning resources.
This document provides an introduction to functional programming in JavaScript. It discusses key functional programming concepts like pure functions, immutable data, and referential transparency. It explains how JavaScript supports functional programming with features like anonymous functions, closures, and higher-order functions. The document also demonstrates functional programming tools like filter, map, reduce, currying, and function composition. It provides examples of how to write pure functions and avoid side effects. Finally, it encourages readers to start applying these concepts like writing pure functions, using currying, and embracing functional composition.
The next version of JavaScript, ES6, is starting to arrive. Many of its features are simple enhancements to the language we already have: things like arrow functions, class syntax, and destructuring. But other features will change the way we program JavaScript, fundamentally expanding the capabilities of the language and reshaping our future codebases. In this talk we'll focus on two of these, discovering the the myriad possibilities of generators and the many tricks you can pull of with template strings.
JavaScript is evolving with the addition of modules, platform consistency, and harmony features. Modules allow JavaScript code to be organized and avoid naming collisions. CommonJS and AMD module formats are used widely. Platform consistency is improved through polyfills that mimic future APIs for older browsers. Harmony brings language-level modules and features like destructuring assignment, default parameters, and promises to JavaScript. Traceur compiles Harmony code to existing JavaScript.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
Flutter is a popular open source, cross-platform framework developed by Google. In this webinar we'll explore Flutter and its architecture, delve into the Flutter Embedder and Flutter’s Dart language, discover how to leverage Flutter for embedded device development, learn about Automotive Grade Linux (AGL) and its consortium and understand the rationale behind AGL's choice of Flutter for next-gen IVI systems. Don’t miss this opportunity to discover whether Flutter is right for your project.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
4. Components
Breaking UI into a compoent hierarchy is logical
They usually great at one thing
Components are highly reusable epecially in large apps
JSX is great for this
14. Reducer composition
It helps to split data handling logic, when each of reducers is
managing its own part of the global state
Redux provides util combineReducers() that makes it easy to use.
22. Examples
function () { return 1; }
() => { return 1; }
() => 1
function (a) { return a * 2; }
(a) => { return a * 2; }
(a) => a * 2
a => a * 2
function (a, b) { return a * b; }
(a, b) => { return a * b; }
(a, b) => a * b
function () { return arguments[0]; }
(...args) => args[0] // ES6 rest syntax helps to work without 'arguments'
() => {} // undefined
() => ({}) // {}
23. Spread operator
Math.max(-1, 5, 11, 3) // 11
Math.max(...[-1, 5, 11, 3]) // 11
Math.max(-1, ...[5, 11], 3) // 11
// example from Tic Tac Toe React
// with ES6 spread operator
function getMaxElement(arr) {
return Math.max(...arr);
}
// without ES6 spread
function getMaxElement(arr) {
return Math.max.apply(null, arr);
}
25. Destructuring
// Can work with objects
let {one, two} = {one: 1, two: 2} // one = 1, two = 2
// And arrays
let [,,x] = ['a', 'b', 'c', 'd']; // x = 'c'
// Is that it? Nope, array destructuring works with iterable objects
// Like strings
let [x,y] = 'abc'; // x='a'; y=['b', 'c']
// And Set
let [x, y] = new Set(['x', 'y']); // x = 'x', y = 'y'
// and etc.
// It's works great with rest operator
let [x,...y] = 'abc'; // x='a'; y=['b', 'c']
// And looks great in functions
function ([x, y, ...rest]) {...}
26. let, const
let and const are block scoped
let and const don't get hoisted have TDZ (Temporal Dead Zone)
Variables de ned with let/const can't be de ned more than once
in the same scope
27. Template strings
// Can contain multiline strings
let multiline = `line 1
line2`; // and spaces matter
let x = 1;
// Can evaluate variables, or expressions inside ${...}
let str = `${x + 41}` // str = '42'
// Can be tagged
function firstString(stringsArray, ...allValues) { // using the new ES6 rest syntax
// allValues is array of values passed inside ${}
return stringsArray[0];
}
let firstStr = firstString `Some text ${x} bla-bla`;
// firstStr = 'Some text ';
