If you are learning programming most probably you have heard about Javascript a lot of time. As of 2020, Javascript is arguably the most popular programming language to ever exist. Let’s see what is so special about Javascript, what we can achieve with it.

What is Javascript and where is it used?

Javascript is the language that make web pages alive. Along with HTML and CSS, it is one of the core component of web technologies. While HTML is responsible for structure of a web page and CSS is responsible for style, Javascript bring interactivity and behavior to web pages.

By means of interactivity whenever you see a web page does more than sit there and show some static information, you can bet that Javascript is involved there. It allows you to dynamically update your content, control multimedia, change your style on the go and a lot more than that.

Briefly Javascript is a scripting language that allows you to implement complex features on web pages.

If you don’t know what a scripting language is, basically it is also a programming language. The difference between the two is that scripting languages do not require the compilation step but rather interpreted. For example, a C program must needs to be compiled before running but a scripting language like Javascript or PHP need not be compiled.

Why is it called Javascript?

A lot of developer on their early stages of learning programming have the same confusion about the Javascript and Java. They are completely different programming languages. The reason why the names looks similar is a result of a marketing tactic when the Javascript first created in 1995. It was first named as LiveScript and then Netscape changed its name to Javascript because of the popularity of Java in that time. It also known as ECMAScript after its standardization in 1997.

It is, but, it falls under the infamous subcategory of "scripting languages", which, technically, by definition are PLs.

Though, this could just be satire, and I could be wooshed.
