Introduction to JavaScript

JavaScript is a platform-independent, event-driven, interpreted client-side scripting language developed by Netscape. Initially, it was called LiveScript (beta release) but soon it was renamed and called JavaScript when it's the first version 1.0 was released. Its latest version is 1.8.5 (released in July 2010). It follows the ECMAScript standard. Now, JavaScript is a trademark of Oracle Corporation.

JavaScript is also a spontaneous and rewarding language which is especially important when you are just getting started with software development. The community support is very good, hence due to that reason, JavaScript has become the primary choice for current-era apps as it has the support of multiple platforms such as mobile apps, desktop, and web applications, thus using the knowledge of JavaScript, the developers can craft the application in no time.

Today, JavaScript is most commonly used by all browsers to manipulate HTML elements, validate input, and communicate with servers, and so on. JavaScript is a case-sensitive language and almost everything in JavaScript is an object.
