JavaScript is a programming language that is one of the top three for the production of Internet content. It is classified as an untyped, interpreted, and object-based language that was developed in 1995.

Its developer was mastermind Brendan Eich, and he and his team came up with Mocha (JavaScript’s first name) in only ten days. Eich wrote a prototype in order to secure JavaScript from competitors. It was released under Netscape. Between 1996 and 1997 a JavaScript standard specification was determined, enabling other browsers to apply it.


Netscape came to the conclusion that a more dynamic World Wide Web was necessary, i.e. a programming language alongside HTML. They wanted to enable web designers and programmers more space for more plugins and images with a directly entered code in the markup of the web page. As they progressed with Eich, they figured out that the new programming language would complement Java and it meant the exclusion of other languages (Python, for example, and others). Server-side implementations were developed and added in the new millennium.

Standardization and Specification

The first step Netscape undertook was the submission of JavaScript to the Standard Specification Organization Ecma International for setting up a specification. The first language specification was released under the name ECMAScript. JavaScript became the most popular of all implementations, even more, desirable than Microsoft’s Jscript. The second standard was released the following year, in 1998, in order to comply with the ISO standards and it was called ECMAScript 2. The third standard release ECMAScript 3 represented the main basis for JavaScript we know today.

Microsoft and JavaScript

When the fourth standard release came out, ECMAScript 4, Microsoft showed some interest and implemented certain proposals. Still, with time, that interest faded away, and Microsoft did not want to use JavaScript in Internet Explorer even if it was only the logical thing to do given that there were no other competitors and they had no proper implementation on the.NET server. JavaScript was kind of “put on the shelf” until 2005 when Mozilla and Eich came again together with Ecma International and created a new standard for XML (EX4), which eventually led to a collaboration with Macromedia that used the new EX4 standard.

How Does It Work?

JavaScript covers web pages, video games, online programs, and a variety of other features. All modern-day browsers incorporate Java automatically without the need of any additional plug-ins or extensions. JavaScript works as a built-in component. Moreover, the majority of websites rely on JavaScript for operation.

JavaScript is a multiparadigm programming language which means it supports an array of tools and features. Its API (Application Programming Interface) supports text operations, regular expressions and DOM is also enabled. However, graphics enhancement, networking, and storage are not specifically supported but depend on the host environment.

JavaScript developed from a client-based to a basically all-around presence and found its way into non-online software like pdf. Many confuse JavaScript with Java, and it is true that they are similar regarding standard libraries, syntax, and the name of course, but JavaScript’s design is significantly different, and they are not interchangeable.
