What is JavaScript?

JavaScript is a powerful scripting language that can be added with HTML to make the webpage more interactive. Javascript was created by Brendan Eich in Netscape in 1995, then its name was LiveScript, which was later changed to JavaScript.

Numerous software engineers consider Javascript and Java identified with one another, yet in actuality, these two are totally not quite the same as one another and there is no association between them. Where Java is a very complex programming language, Javascript is only a light-weighted scripting language.

Javascript is client-side scripting, which means it runs on the user's browser. Whenever the user sends a request for a webpage, then the server also sends the JavaScript code along with the HTML of that page to the browser, now the responsibility of this browser is that it executes the code of that JavaScript as needed.

You can see the javascript code on your program since it keeps running on the program. On the contrary, you might have heard about server-side programming such as PHP, ASP.Net, JSP, etc. All of these languages are created on the program browser but not run on the server and its output is converted to HTML and appears in the browser and its code you cannot see on the browser.
