Learn JavaScript?

If you’re reading this, you’re most likely interested in things like video games, intriguing apps, animation, interactive webpages and maybe even robotics. That’s because programming languages like JavaScript are behind all of these things.

Why you need to learn a programming language

A programming language is basically a collection of instructions for a computer. Most of these languages are user-friendly, meaning that the instructions are written in terms understandable by humans (using English words), and are then translated into computer-speak (0’s and 1’s) for the computer to understand. At least one of them is essential to know if you want to be a web developer.

A programming language goes hand-in-hand with HTML and CSS, literally bringing webpages to life. Ok, well maybe not literally. But you see, in the old days of the Web, all pages were ‘static’, meaning that they were perfectly still and unchanging. If a user made a request for more information to pop up on the page, the whole page would have to be reloaded for the change to take place. Ugh. But today, thanks to the development of programming languages, information can be fetched from the server and updated on a webpage without that page having to be reloaded. These kinds of developments have changed the way we experience the Web; it has now become a place that humans can interact with. Programming languages make this possible by enabling animation, video, audio, news feeds, surveys, log-in, live chats, search bar navigation and mouse-rollover effects (to name a few features). And they’re not just useful for Web development, but for developing apps and games too.

Why JavaScript?

In the computing world, there are many of these languages to choose from: Python, Java, C, Ruby, PHP, and Perl are among the number. JavaScript is one of the most widely used programming languages out there, for good reasons. To help you realize why you should learn JavaScript, here are four:

Universal compatibility

First of all, it’s built into every common web browser, which basically means that anything you create using JavaScript can be used by virtually everyone on the web. No incompatibility there!

It’s easy to use

Secondly, it’s easy to use. There are no programs to install on your computer, and you don’t need to buy anything to edit it. Since JavaScript is all text based, all you need to write it is a plain text editor like Notepad or TextEdit (both of which come free with any Windows or Mac OS operating system). There are some alternative plain text editors out there that you can use too – ones which highlight certain code to make it easier to read, like Notepad++.

JavaScript libraries – jQuery

Thirdly, there are many libraries available for JavaScipt. These libraries are collections of pre-written JavaScript code which act kind of like shortcuts; they take complex functions that would normally take many lines of code and shorten them to a few lines. It makes writing JavaScript a whole lot easier. By far the most popular library is jQuery, used in millions upon millions of the most visited websites.


Finally, given its huge presence on the Internet, it’s no wonder JavaScript programming skills are among the most sought-after by employers in the I.T industry. For web developers, alongside HTML and CSS, JavaScript is a core computer language to know. In fact, it is projected for the U.S that by 2020, jobs in the I.T industry will grow by 22% – faster than average.*
