Learn JavaScript. JavaScript is a programming language that allows you to implement complex things on web pages.
Every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, or interactive maps, or animated 2D/3D graphics, or scrolling video jukeboxes, and so on — you can bet that JavaScript is probably involved. Learning pathway JavaScript is arguably more difficult to learn than related technologies such as HTML and CSS. Before attempting to learn JavaScript, you are strongly advised to get familiar with at least these two technologies first, and perhaps others as well. Start by working through the following modules: Having previous experience with other programming languages might also help. After getting familiar with the basics of JavaScript, you should be in a position to learn about more advanced topics, for example: Modules This topic contains the following modules, in a suggested order for working through them.

Prefix and Postfix increment/decrement operators Prefix increment / decrement operators are operators that first increase the value of the variable by 1 (increment) or decrease the value of an expression / variable by 1 (decrement) and then return this incremented / decremented value.

They are used like (variable)++ [increment] or (varaible)-- [decrement] Syntax --variable ++variable variable-- variable++ Example var x = 15; var y = x++; console.log(y); console.log(x); var a = 15; var b = ++a; console.log(b); console.log(a); JavaScript.

JavaScript is a powerful, complicated, and often misunderstood computer language. It enables the rapid development of applications in which users can enter data and view results easily. The primary advantage to JavaScript, which is also known as ECMAScript, centers around the Web browser, thus having the ability to produce the same results on all platforms supported by the browser. The examples on this page, just like Google Maps, run on Linux, Windows, and Mac OS. With the recent growth of numerous JavaScript libraries it is now easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. What you should already know JavaScript is a very easy language to start programming with. There are many other technologies that can be integrated into and developed along with JavaScript that are beyond the scope of this document.
