Introduction to JavaScript programming - For beginnners

What is JavaScript?

JavaScript (Created by Brendan Eich on 4th December 1995, ) is basically a client-side scripting language. Here the term client-side refers to the design section of a website. Normally called as the Front-end part. Design section is that section where all information is displayed or in simple words, the user interacts with, such as the layout of a website, images, videos, its content and basically all visible stuff.

This language is mainly used in the collaboration with HTML and CSS. Where HTML is used to display content and CSS makes that content look better (More colorful and systematic). Here what javascript comes into action. It makes that content more fluid and interactive.

So what made javascript to be counted into the list of top 10 programming languages? let’s find out. But before that let’s see what definition has to offer.

Definition- “JavaScript is a client-side scripting language, which means the source code is processed by the client’s web browser rather than on the web server. This means JavaScript functions can run after a webpage has loaded without communicating with the server.” 

Why it was created?

  1. Surprisingly after the onset of JQuery , I have met a lot of people who are not clear with the basics of Javascript, however, do everything using JQuery. I would recommend everybody to be very clear with the basics first before learning any other Javascript-based frameworks.
