What is Javascript?

JavaScript is a simple and easy-to-learn programming language as compared to other languages such as C++, Ruby, and Python. It is a high-level, interpreted language that can easily be embedded with languages like HTML. It was developed by Netscape Communications Corporation, Mozilla Foundation, and ECMA International. Brendan Eich is known as the creator or designer of the JavaScript programming language.

Initially, JavaScript was known as LiveScript, but later Netscape changed its name to, JavaScript. Some amazing features of JavaScript are as follows −

  • Lightweight, interpreted language.

  • Easily embedded with languages like HTML, CSS, and Java.

  • Also works as a client-side scripting language, which helps in creating dynamic web pages.

JavaScript is an open source and cross-platform language and therefore mostly used for creating network-centric applications. Nowadays it has become an inseparable part of the core technologies of the internet. JavaScript is used in web technologies to make web pages interactive. Along with HTML and CSS, JavaScript is widely used in web servers and databases. Hence its wide popularity among these kinds of websites. In order to begin with JavaScript, you can use any simple text editor such as Notepad. If you want to pursue a career in development with JavaScript, then you are in the right place. In this article, we will introduce you to some of the best resources that provide free online tutorials to learn JavaScript.

JavaScript - History

JavaScript was originally developed as LiveScript by the Netscape in the mid 1990s. It was later renamed to JavaScript in 1995, and then became an ECMA standard in 1997. It is a client-side scripting language for web-based applications, and it is supported by almost all web browsers available, such as Google Chrome, Mozilla Firefox, Apple Safari, Edge, etc. In 1995 Netscape was in competition with Microsoft and that’s why they approached Sun Microsystems, which was about to launch a new programming language JAVA. Java was a programming language which had all the features of Object Oriented Programming. Unlike C/C++ Java’s compiled bytecode was machine independent, it could run on different operating systems.

It could also develop applets which could run on websites. Due to all these features, Java became very popular language. Java was used for system programming and applet development but there was still a need for a scripting language for websites to enhance the user’s interactivity with the website. Netscape in collaboration with Sun Microsystems thought of developing a scripting language especially for Netscape to compete with Internet Explorer of Microsoft which was gaining popularity. In early 1995 Netscape contracted Brendan Eich to design a scripting language. It resulted in the birth of LiveScript. This Scripting language could easily be written directly inside HTML and could run on Netscape browser.
