What is JavaScript?

JavaScript is a very powerful client-side scripting language. Client-side scripting is performed to generate a code that can run on the client end (browser) without the need for server side processing. Basically, this type of script is placed inside an HTML document.


JavaScript is primarily used to enhance Interaction with a user with a webpage. In other words, you can make your webpage more vibrant and interactive with the help of JavaScript. JavaScript is also being widely used in game application development and mobile application development.

Currently there are 100 of programming languages ​​and everyday new Programming Language is being created but few of them are Powerful and good programming languages ​​and JavaScript is one of them.


If you want to become a good Software Engineer then you must have a good knowledge of JavaScript. Let us now tell you about the history of JavaScript History.
