In this article we will discuss about JavaScript programming language. Here, you will learn about the meaning of JavaScript programming language, its features, history, applications, and why should we learn it? So let's start with the meaning of JavaScript programming language.

JavaScript: Intro, History, Features, Applications, Why should Learn?

What is JavaScript programming language?

JavaScript is a powerful programming language which was mainly designed for web. JS is used as an abbreviation of JavaScript. JavaScript is used for scripting web pages. The programs written in JavaScript programming language are known as scripts. JavaScript is a easy to learn and powerful programming language which supports multi paradigm like imperative, and functional, etc. JavaScript programming language is a just-in-time compiled programming language. JavaScript is also considered as object oriented programming language as it supports the features of object oriented programming approach. JavaScript follows all the concepts like class, inheritance, abstraction, polymorphism and encapsulation of object oriented programming approach. 

JavaScript programming language is a high level and dynamically typed programming language. HTML and CSS languages are used to give structure and style to web pages and JavaScript is used to give the interactive elements like popup menus, animations, form validations, etc. in web pages in order to engage users. JavaScript is a light weighted and interpreted programming language. JavaScript programming language is highly complementary to HTML and Java programming language. JavaScript is originally designed to make web pages more interactive but now it is also used in many other areas like mobile application, server side development, etc.

History of JavaScript programming language

There are various facts related to the history of JavaScript programming language. So, now let's discuss about the history of JavaScript programming language in detail.

In September 1995, Netscape programmer Brendan Eich develop the JavaScript scripting programming language. Brendan Eich is the father of JavaScript programming language and he had developed JavaScript in programming language within 10 days. 

At first the programming language was named "Mocha"and later it was replaced with "LiveScript" by the marketing team. But due to some trademark reasons later they named it "JavaScript". The idea of JavaScript name was from the Java programming language which was very popular at that time. But Java and JavaScript does not have anything in common.

Features of JavaScript programming language

There are various features available in JavaScript programming language which makes it a powerful and popular programming language. So, now let's discuss in detail the main features of JavaScript programming language.

1. Object oriented programming

JavaScript programming language is considered as an object oriented programming language and it supports the different features of object oriented programming approach. JavaScript programming language follows all the concepts of object oriented programming approach like class, inheritance, polymorphism, abstraction, and encapsulation, etc.

2. Platform independent

JavaScript programming language is platform independent or cross platform programming language which means that the programmers can easily use the codes written in in JavaScript programming language in any operating system which are supported by Netscape like Windows, Macintosh, etc.

3. Validating user's input

JavaScript Programming Language also provide the feature of validation of user's input which is commonly known as form validation. Form validation saves the time and it checks whether all fields are filled or not in a form before sending it to the Servers.

4. Lightweight

JavaScript programming language is a easy to use, lightweight and powerful scripting programming language. There are no variables included in the codes that are written in JavaScript programming language. JavaScript programming language uses objects for performing every operation.

Some additional features of JavaScript programming language are as follows

• JavaScript programming language is an interpreted programming language.

• JavaScript is widely used for making webpages more interactive.

• JavaScript programming language is a fast programming language.

• JavaScript programming language provides a vast range of frameworks and libraries.

• JavaScript is used in developing mobile apps, games, web applications, web servers, etc.

• JavaScript programming language is supported by all main browsers.

Applications of JavaScript programming language

JavaScript programming language is mainly designed for scripting web pages but now after getting popular it is also used in many other areas. So, now let's discuss in detail about the applications of JavaScript programming language.

• Web applications

JavaScript programming language is used by the programmers in developing various web applications. JavaScript is originally developed for web. With the help of different frameworks of JavaScript programming language, the programmers can develop different types of web applications and also give them a interactive look. For example: JavaScript is used in the development of popular Google maps.

• Mobile applications

Programmers also use different frameworks of JavaScript programming language for developing applications for mobile devices. React Native is the most used framework of JavaScript programming language which is used in mobile applications and we can create mobile applications for different operating systems with the help of React Native. The apps which are developed by using JavaScript programming language are Netflix, Uber, PayPal, etc.

• Web servers

JavaScript programming language is also used by the programmers in developing web service. Programmers can develop different type of powerful, robust and fast web service with the help of Node .js  framework of JavaScript programming language. The service which are developed by using Node .js take very less time in buffering.

• Games

Programmers also use JavaScript programming language in developing different types of games with the help of several libraries and frameworks. By using JavaScript programming language for developing games, beginner programmers can check their skills. The games which are developed by using HTML5 and JavaScript are Swooop, HexGL, CrossCode, etc.

• Web development

JavaScript programming language was mainly used in web development. With the use of JavaScript programming language programmers can add interactive elements like popup menus, form validation and animations in web pages in order to engage users. JavaScript programming language is also used in developing different types of websites.
