History of Javascript

Basically The Brendan Eich created JavaScript in 1995 while he was at Netscape Communications Corporation, the creators of the legendary Netscape Navigator web browser.And at the time, the Java coding language was rapidly gaining traction and Netscape Communications was working to make it available in Netscape Communicator.

In the beginning the early versions of JavaScript were called Mocha. Not long after a Mocha prototype was introduced into Netscape Communicator (May 1995), it was renamed to LiveScript, purely because the world Live was better for marketing. It was renamed again in December of the same year, this time into JavaScript.
