Writing Classes in Javascript
JavaScript / General Development
Wrtting classes in Javascript doesn't give full functionality of an object oriented language, but it atleast gives data hiding and encapsulation which are very useful specially when javascript is not a strongly typed language. It is very useful in cases when you need to handle multiple objects , instead of having arrays for all kinds of variables and then managing those arrays in methods you can just write a class to handle one object and then make many instances of that class. This also gives the namespace resolution to the variables so that you can avoid using global variables and still use variables across procedures.

Introduction to Functions
JavaScript / Getting Started
A function is an assignment that JavaScript can take care of for you. It is a technique used to isolate a group of instructional code so that other parts of the application can depend on it to provide them with a reliable result. There are two main categories of functions you will be using in JavaScript: those that have already been created for you and those you create in your code.

Tutorial: Introduction to JavaScript
JavaScript / Getting Started
JavaScript is an easy-to-learn programming language which can be built into Web pages, so that it executes from within the browser rather than on the web server.

In this introduction we concisely look at the main programming points of the JavaScript language.

Functions
JavaScript / Getting Started
Sometimes instead of just adding your javascript to the page and having the browser perform the tasks as soon as the script is read, you might want your javascript to be performed only upon the detection of a certain event. A function is a block of code which can be called from any point in a script after it has been declared. It is basically a compartmentalized JavaScript designed to accomplish a single task.

Arrays
JavaScript / Getting Started
Arrays are a fundamental part of most programming languages and scripts. Arrays are simply an ordered stack of data items. Each element of the array can store its own data, just like a variable, thus you can say arrays are collections of variables. Items can be added and removed from the array at any time, also their value can be changed easily. One other feature of the arrays, which is specific to JavaScript is that the elements in the array can be of different types.
