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

Today, JavaScript is most commonly used by all the 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.

ECMA Script

ECMAScript is a scripting language standard developed by Ecma International. This standard is widely followed by client-side scripting languages on the Web such as JavaScript, JScript and ActionScript. It's latest version is ES5.1 and ES6 is expected to release in mid 2015.

JavaScript VS JScript

JScript is another version of JavaScript developed by Microsoft. It was released with Internet Explorer 3.0 and based on Netscape JavaScript. It's latest version is 9.0 (released in Mar 2011). The main difference between JavaScript and Jscript is that JScript supports some additional commands to access ActiveX and the local computer as compared to JavaScript. Also, these commands are intended for use on intranet sites and for the browser Internet Explorer.

In many other cases JScript behaves differently from JavaScript, suppose you have a variable and element on the page having same ID like as-

var temp = 'Hello JavaScript';
document.getElementById('temp').innerHTML = temp;

In JavaScript, this code will run without error but JScript gives an error since JScript does not recognize the difference between variable temp and element having Id temp. JScript treats both of them as a single object.
