An introductory presentation I'm doing at my workplace for other developers. This is geared toward programmers that are very new to javascript and covers some basics, but focuses on Functions, Objects and prototypal inheritance ideas.
This document provides an overview of Metro style apps and the C++ language features for building them. It compares the architecture and frameworks of Metro style apps to desktop apps. It then summarizes key C++ language features for Metro style development including reference types, memory management, pointers, events, generics and libraries. The document promotes C++ for building high performance Metro style apps and provides examples of key language concepts.
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.
Stamps - a better way to object compositionVasyl Boroviak
The document discusses an approach called "stamps" for composing object behaviors in a declarative way, as an alternative to class inheritance. Stamps are like classes/factories but specify behaviors through composable metadata rather than inheritance. A stamp implementation is shown that allows defining initializers, methods, properties, and static properties and composing them to create new stamps. The stamps approach is compared to configuring classes through annotations and dependency injection in Java.
The document provides an outline of a lecture on object-oriented JavaScript and inheritance. It covers key concepts like objects, properties, methods, object literals, constructor functions, and prototype inheritance. It discusses creating and accessing objects, adding and removing properties, passing objects by reference, comparing objects, and the prototype chain. Private and privileged methods and properties are explained. Different approaches to implementing inheritance like prototype chaining are also summarized.
This document discusses monad transformers in Scala. It begins by introducing the OptionT monad transformer, which lifts an Option into a monad M. It defines the point and map methods for OptionT to make it an instance of the Monad type class. Later sections discuss using monad transformers to compose monads like IO and Option that normally do not compose, and how this allows embedding domain-specific languages within programs.
JavaScript objects must implement certain standard properties and methods. Objects have a prototype property that is either an object or null, and prototype chains must have finite length. The typeof operator returns a string indicating the type of a variable or value. JavaScript supports basic types like undefined, null, boolean, number, string, and object. Functions are objects that can be called, and have properties like length and arguments. Variables declared with var have function scope, while variables assigned without var have global scope. Arrays, objects, and functions can be declared using various syntaxes. JavaScript uses prototypal inheritance rather than classes.
This document provides an agenda and overview for a presentation on JavaScript. It discusses JavaScript's history and popularity, current implementations of JavaScript engines in browsers, and proliferation of JavaScript frameworks. The agenda outlines discussing objects, functions, scope, primitives, common mistakes, inheritance, best practices, modularity, and more. It also includes code examples demonstrating functions, closures, scope, operators, and error handling in JavaScript.

This document provides an overview and introduction to building a basic fraction calculator app in Objective-C. It begins with an overview of the project architecture using the MVC pattern with a Fraction model class to represent fractions, a Calculator class to perform operations, and a ViewController class to manage the user interface. It then details the implementation of each class, including the Fraction class with methods for creating, modifying, and performing operations on fractions, the Calculator class for setting operands and performing operations, and the ViewController class for handling user interface events and updating the display.
Scala is a multi-paradigm language that runs on the JVM and interoperates with Java code and libraries. It combines object-oriented and functional programming by allowing functions to be treated as objects and supports features like traits, pattern matching, and immutable data structures. The Scala compiler infers types and generates boilerplate code like getters/setters, making development more productive compared to Java. While Scala has a learning curve, it allows a more concise and scalable language for building applications.
The document provides information about a JavaScript course including:
1. The course consists of 5 lectures and 5 labs and is evaluated based on projects, assignments, labs and quizzes.
2. The lecture outline covers introduction to JavaScript, syntax, built-in objects and functions.
3. JavaScript was invented by Brendan Eich at Netscape and first appeared in the Netscape Navigator browser in 1995.
This document discusses best practices for writing JavaScript code, including using object-oriented patterns, object hierarchies, and the prototype property to organize code and prevent naming collisions. It also recommends writing reusable code by parameterizing functions, using object literals as flexible parameters, and loading JavaScript on demand. Additionally, it suggests separating content, CSS and JavaScript into different files and reducing file sizes for production.
RxSwift is a library for reactive programming with Observables that provide asynchronous, event-based data streams. The document discusses key concepts of reactive programming like data flows, propagation of change, and functional reactive programming. It provides examples of using RxSwift to create Observables from various sources and applying operators like map, filter, and combineLatest. Validation of form fields is demonstrated by combining Observables of text changes and checking field values and formats.
The document discusses the ECMAScript 262 specification. It provides an overview of the history and structure of ECMAScript, describes the different types and objects in ECMAScript like primitive values, references, and host/native/built-in objects. It also summarizes type conversion methods like ToPrimitive, ToBoolean, ToNumber etc. and how operators like equals and new work in ECMAScript.
The document discusses some of the "obvious secrets" of JavaScript. It covers:
1. All objects must implement certain standard properties and methods like prototype, get, put, etc.
2. The typeof operator and how it returns different strings for different types.
3. How values can be converted between types using methods like toString, toNumber, etc.
4. Ways to declare variables, functions, arrays and objects in JavaScript.
5. Core concepts of the language like scope, context, inheritance and how JavaScript uses prototypal inheritance rather than classical inheritance.
The document provides an overview of JavaScript core concepts including:
- A brief history of JavaScript originating from LiveScript and becoming ECMAScript.
- Core misunderstandings about JavaScript being object-oriented and prototype-based.
- Key concepts like objects, functions, scope, 'this', arguments, invocation, and closures.
- How functions work with parameters, return values, and different invocation styles.
- Global versus function scope and how closures allow accessing outer function variables.
- Resources for further reading on JavaScript fundamentals.
This document discusses using case classes in Scala to represent JSON data in a type-safe way. It begins with an object-oriented representation of JSON using regular classes, then refactors it to use case classes. Case classes allow simpler construction without "new", enable pattern matching, and prevent unintended extension through the "sealed" keyword. The document concludes that the functional approach using case classes and pattern matching is better than the object-oriented approach for representing and extending data types in a type-safe way.
Functional programming in Scala. Looking at various examples of defining a program first and executing it at some later stage, separating pure functions from side effects.

My JSConf.eu talk about next-gen JavaScript metaprogramming features, starting with ES5's new Object APIs and then focusing on the forthcoming Proxy object, approved for the next ECMA-262 Edition. This is beautiful work from Tom Van Cutsem and Mark Miller, with Andreas Gal helping on the implementation front -- proxies are already shipping in Firefox 4 betas.
The document provides an overview and agenda for an Advanced JavaScript course. It covers JavaScript history from 1995-1996, how JavaScript is used today both on the client-side and server-side with Node.js. It also discusses JavaScript language fundamentals like data types, objects, arrays, functions and prototypes. The agenda includes deep dives into these topics with examples and exercises to practice working with objects, arrays, functions and prototypes in JavaScript.
The document discusses JavaScript objects and functions. It explains that JavaScript objects are collections of name-value pairs similar to dictionaries. Functions in JavaScript are objects that support function call operations. The document also covers constructor functions, prototypes, closures, and namespaces in JavaScript.
In JS: CLASS <=> Constructor FN
new FN() => FN() { this }
FN = CLASS (FN = FN, FN = DATA)
Objects
Prototype / __proto__
Inheritence
Rewriting / Augmenting
built in objects
This document discusses JavaScript functions. It explains that functions are first-class objects that can be stored in variables, passed as arguments, and returned from other functions. It provides examples of defining, calling, and returning values from functions. It also covers optional parameters, anonymous functions, higher-order functions, and functions as methods.
The document discusses JavaScript and some of its key features:
- JavaScript is the programming language of the web browser and was originally developed by Netscape under different names before being standardized.
- JavaScript uses a prototypal object model instead of classes, with objects inheriting directly from other objects via prototypal inheritance chains rather than from classes.
- The "new" keyword is used to create objects but can give the misleading impression of classes; functions can also be used to create objects without "new" by returning the object.
- jQuery uses CSS-style selectors to select elements and create wrapped sets that allow accessing and manipulating elements
- Objects in JavaScript can contain functions and properties, and functions are also objects that can be passed around and assigned to properties
- Event handling in jQuery provides a cross-browser way to attach multiple handlers to events and prevent default behavior
- jQuery methods like bind(), live(), delegate() allow attaching handlers to current and future elements, and events can be hijacked to make AJAX requests instead of full page posts
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 Ember objects and their advantages over plain JavaScript objects (POJOs). It describes how Ember objects use getters and setters to synchronize state, and features like computed properties, observers, and bindings that help manage state changes. Computed properties allow defining derived properties, observers define callbacks for property changes, and bindings automatically synchronize linked properties. The document gives examples and best practices for using each feature.
This document provides an overview of JavaScript basics including:
- The history and creation of JavaScript in 2 weeks by Brendan Eich.
- Language basics like syntax, variables, objects, functions, and inheritance.
- Tools for JavaScript development like Firebug and jsLint for debugging and linting.
- Best practices like unobtrusive JavaScript, namespaces, and automated testing.
- Resources for further learning JavaScript like books and websites.
The document discusses various approaches and best practices for testing JavaScript code. It covers topics like behavior-driven development with Jasmine, testing asynchronous code using spies, waiting for asynchronous operations to complete, testing interactions with the DOM, testing legacy untested JavaScript code, and setting up continuous integration for JavaScript tests.
The document discusses class and object-oriented programming concepts such as classes, objects, member functions, and constructors. It provides examples of class declarations and definitions, and how to create objects and call member functions. The document also covers constructors, initializer lists, destructors, function templates, and class templates.
This document summarizes some lesser known features of the ActionScript programming language. It begins by discussing various operators like equality, logical operators, and type casting. It then covers topics like namespaces, arguments, rest parameters, object references vs copies, and global functions. The document concludes by noting some gotchas and peculiarities in ActionScript, such as casting behaviors and behaviors of the Array and Date classes.
Software written in such way might look unconventional, and has a bit of a learning curve. The talk is to show that the advantages it brings make it a viable choice.
The document provides an overview of the YUI library. It discusses:
1) What YUI is and its main components like the JavaScript library, CSS foundation, documentation tools, build tools, testing tools, and more.
2) Some of the core utilities included in YUI like Event, Node, YUI Global Object, Array, mix, extend, augment, Object, merge, clone, and Module.
3) How to use YUI features like the loader, events, DOM events, custom events, Node, IO, Transition, and infrastructure components like Base, Attributes, Plugin, and Widget.
The document provides an overview of JavaScript for PHP developers. It discusses similarities and differences between JavaScript and PHP syntax, including variables, arrays, conditionals, loops, functions, objects, prototypes, and more. It also summarizes the built-in JavaScript API, including global functions, constructors, and properties and methods of objects like Object, Array, Function, String, Number, Math, Date, and Error.
Object class represents one of JavaScript's data types. It is used to store various keyed collections and more complex entities.

2. Why JavaScript?
Simple
Multi paradigm
Works on the server and the browser
Lots of libraries
JSON

3. I heard it sucks, its broken
Implicit globals
Confusing this keyword
Confusing OO features, lack of class
syntax
Type coercion
Thursday, September 20, 12
5. Type system
Weak typing means that a language
implicitly converts types when used.
A programming language is said to use
dynamic typing when type checking is
performed during run-time as opposed
to compile-time.

10. Type system
Avoid coercion
Define API’s with clear types
Use the === operator
Read the spec or this article http://

javascript-coercion-demystified.html

11. Type system
/**
* Adds two numbers
*
* @param {Number} a
* @param {Number} b
* @return {Number}
*/
function add(a, b) {
return a + b;
}
/**
* Returns the sumatory of a list of numbers
*
* @param {Array<Number>} list
* @return {Number}
*/
function sum(list) {
return list.reduce(add, 0);
}
Thursday, September 20, 12
12. Type system: Casting
Use the constructors Number(‘3’) === 3
Use the prefix + operator +‘3’ === 3
Use the infix + operator 3 + ‘0’ === ’30’
Use the prefix ! operator !!1 === true

13. Variables
Variables are function scoped
The var operator is evaluated statically
It instantiates all the variables on the
current scope
It assigns them the undefined value
Assignment on variables that have not
been instantiated create a global
Thursday, September 20, 12
14. Variables
// Hoisting: Cannot read property 'name' of undefined
var name = user.name
, user = {name: 'John'};
// This creates a global!
foo = ‘bar’;
// Function scope
var a = 10;
if (true) {
var a = 20;
}
(function () {
var a = 30;
}());
a == 20;
Thursday, September 20, 12
15. Functions: Declaration vs Expression
// Function declaration (static)
function add(a, b) {
return a + b;
}
// Function expression (runtime)
var add = function (a, b) {
return a + b;
}
// Function named expression (runtime)
var recursiveAdd = function inc(a, b) {
if (a > 100) return a;
return inc(a + b, b);
}
Thursday, September 20, 12
16. Functions: Higher order
Functions can accept functions as a
parameters and can return functions
Functions are objects after all, they can
even have attributes!
// Returns a function that will have a delay
function delayFunction(fn, delay) {
fn.delayed = true;
return function () {
setTimeout(fn, delay);
};
});
Thursday, September 20, 12
17. Functions: Closures
Closures are function that “remember”
the variables on their scope
// Gets a function to inspect the given object
function getInspector(obj) {
return function (attr) {
return obj[attr];
};
};
var inspect = getInspector({name: ‘john’, age: 21});
[‘name’, ‘age’].map(inspect) == [‘john’, 21];

18. OOP: Prototypes
Each object can have a pointer to another
object called prototype
When we read an attribute from an
object but its not present, it will try to
find it through the prototype chain
Prototypes are powerful but can be
confusing. Delegation is easy.
Thursday, September 20, 12
20. OOP: Constructors
Calling a function with the new operator
makes it behave like a constructor
The keyword this will point to the newl
object
The constructor will have an implicit
return of the new object
The pointer to the prototype is
assigned to the new object
Thursday, September 20, 12
21. OOP: Constructors
var animal = {eats: true};
function Rabbit(name) {
this.name = name;
this.jumps = true;
}
Rabbit.prototype = animal;
var rabbit = new Rabbit('John')
rabbit.eats === true
rabbit.jumps === true
rabbit.name === ‘John’
Thursday, September 20, 12
22. OOP: The `this` keyword
The global object if its on the main scope
The parent object of a method if the
function is called as a method
The newly created object from a
constructor called with the new operator
The first argument passed to call or
apply inside function code
Thursday, September 20, 12
23. OOP: Constructors
// global
this.Boolean = function () {return false;};
Boolean(2) === false
// method invocation
var button = {
toggle: function () {
this.enabled = !!this.enabled;
}
};
button.toggle();
button.enabled === true;
var toggle = button.toggle;
toggle();
button.enabled === true;
Thursday, September 20, 12
24. OOP: Constructors
// Constructors
function Rabbit(name) {
this.name = name;
}
var rabbit = new Rabbit('John')
rabbit.name === ‘John’;
var rabbit = Rabbit(‘John’);
rabbit.name === undefined;
window.name === ‘John’;
// call or apply
[].reduce.call(
"Javascript is cool!"
, function (memo, a) {
return a + memo;
}
);
