What is javascript?

JavaScript is a programming language initially came as client side language for web browsers. It was created by Brendan Eich in 1995 and was only used to do browser-based development back in those days.

In 1995 it was developed under the name Mocha then it was officially called LiveScript but again renamed as JavaScript by Netscape and deployed in the Netscape Navigator 2.0.


Around November 1996, ECMA International came out with standardization for JavaScript and officially released as ECMA-262 standard in June 1997.

Other major standardization:
