Brendan Eich built JavaScript in 10 days. The web browser Netscape required a "glue language" to allow it to use images and other media with HTML. Mocha was the initial name for JavaScript. Let us know more about the history of javascript and its introduction.

What is JavaScript

All browsers support JavaScript, which is an open-source and widely used client-side scripting language. JavaScript is mostly utilised to improve the webpage's interaction with people by making it more vibrant and interactive. It's also employed in the creation of games and mobile applications.

You can use JavaScript to make a web page more interactive. JavaScript is frequently used in conjunction with HTML and CSS to improve the functionality of a web page by validating forms, producing interactive maps, and showing animated charts, among other things.

The JavaScript engine in the web browser runs the JavaScript code when a web page is loaded, that is, after HTML and CSS have been downloaded. After that, the JavaScript code alters the HTML and CSS to dynamically update the user interface.

A programme that runs JavaScript code is known as the JavaScript engine. Initially, interpreters were used to implement JavaScript engines. Modern JavaScript engines, on the other hand, are usually implemented as just-in-time compilers that compile JavaScript code to bytecode for faster execution.

JavaScript was invented to "bring web pages to life." Scripts are the name for the programmes written in this language. They can be written directly in the HTML of a web page and run when the page loaded.

Scripts are provided in plain text format and executed as such. They don't require any extra setup or compilation to execute. In this regard, JavaScript differs significantly from the Java programming language.

JavaScript is the most widely used interpreted compiled programming language in the world. It's also known as a web page scripting language. It is well-known for web page creation, but it is widely used in numerous non-browser applications. JavaScript can be used tocreate both client-side and server-side applications.

History of JavaScript

Brendan Eich created JavaScript in 1995, and it became an ECMA standard in 1997. The standard's official name is ECMA-262. The language's official name is ECMAScript.

The language was first known as LiveScript before being renamed JavaScript. Many programmers mistakenly believe that JavaScript and Java are the same thing.

In fact, JavaScript and Java have little in common. Java is a powerful programming language, but JavaScript is a simple scripting language. JavaScript's grammar is heavily influenced by the programming language C.

In Netscape Navigator 3, Netscape launched JavaScript 1.1. In the meantime, Microsoft released the Internet Explorer 3 (IE 3) web browser, which competed with Netscape.

IE, on the other hand, came with its own JavaScript implementation, known as JScript. To avoid potential licence concerns with Netscape, Microsoft chose the name JScript.

It was created out of need and is now used to create 95.2 percent (1.52 billion) of all websites, including some of the largest in the world, such as Facebook and YouTube. We wouldn't have popular and helpful web programmes like Google Maps and eBay without it.

The European Computer Manufacturers Association (ECMA) received a proposal for JavaScript 1.1 in 1997. The language was given to Technical Committee #39 (TC39) to standardise in order to make it a general-purpose, cross-platform, and vendor-neutral scripting language.

ECMA-262, a standard describing a new scripting language known as ECMAScript, was developed by TC39 (often pronounced Ek-ma-script).

ECMAScript Is Born

Due to the rapid growth of JavaScript, it became evident in 1997 that the language would need to be properly maintained and managed.

As a result, Netscape delegated the task of developing a language definition to the European Computer Manufacturers Association (ECMA), an organisation dedicated to computer standardisation.

ECMA-262 was the name of the ECMA standards, and ECMAScript languages comprised JavaScript, JScript, and ActionScript.

Between 1997 and 1999, three revisions of ECMA-262 were released, but version 4 was dropped over a decade later due to disagreements over the language's direction and proposed enhancements.

Many of these contentious features, such as generators, iterators, and destructuring assignments, have recently been added to the ECMAScript specification.

JavaScript Today

JavaScript has climbed to become the most popular programming language in the world, despite a difficult start. According to GitHub's 2018Octoverse report, JavaScript has more code repositories than any other language, and the number is continually growing.

Ember, Angular, React, and Vue are just a few of the JavaScript frameworks and libraries that have been built to allow small teams to write powerful and complex online apps in a short amount of time.

JavaScript may now be used to create native mobile apps in addition to client and server software. Due to the ability to share code between the mobile and web worlds, this is becoming increasingly prevalent.

Application of JavaScript

The programming language JavaScript is widely used. Some domains/products that can be built with JavaScript are listed below:

Here are the different types of JavaScript-based applications:


JavaScript enables us to extend the functionality of our website. It facilitates user interaction with the website. For example, clicking buttons, saving information, uploading information to a website, and so on.

Web Servers

Using JavaScript, we can create solid server apps. These servers are built using JavaScript frameworks such as Node.js and Express.js.

Game Development

JavaScript is frequently utilised in the game development business. With the inclusion of HTML5 Canvas, creating 2D and 3D games with JavaScript has never been easier.

Mobile Apps

These days, mobile applications are the most popular means of communication. JavaScript is also used to create mobile apps. We can create android, iOS, and hybrid apps utilising a variety of JavaScript frameworks.

Smartwatch Apps

Pebble.js is a simple JavaScript framework established by Pebble, a popular smartwatch company, that allows a developer to construct a JavaScript application for the Pebble range of watches.

JavaScript is a language that is still developing. It has a lot of other features, which you'll learn about in the following tutorials. You learnt the history of JavaScript is and an overview of the JavaScript language in this session.
