History and evolution of Javascript

JavaScript was created in 1995 by Brendan Eich, while he was working for Netscape Communications Corporation. Initially, it was called Mocha, then it was renamed to LiveScript and later to JavaScript.

The first version of JavaScript was created in just ten days, and it was included in the Netscape Navigator 2.0 browser. JavaScript was designed to add dynamic and interactive elements to static HTML pages, making them more engaging for users. It quickly gained popularity, and other browsers started to include support for JavaScript.

In 1996, Microsoft created its own version of JavaScript, called JScript, which was included in Internet Explorer 3.0. To standardize the language, Netscape submitted JavaScript to ECMA International, a standards organization, in 1997. The result of this effort was the first edition of the ECMAScript standard, which was published in June 1997.

Since then, ECMAScript has undergone several updates, with the most significant ones being ECMAScript 3, released in 1999, and ECMAScript 5, released in 2009. ECMAScript 6, also known as ES6 or ECMAScript 2015, was released in 2015, bringing many new features and improvements to the language.

JavaScript has become one of the most widely used programming languages in the world, with its popularity driven by its versatility and the fact that it can be used for both client-side and server-side programming. Today, JavaScript is used to build everything from simple web applications to complex enterprise systems, and it continues to evolve and improve with each passing year.
