What is JavaScript, and why should I learn it?

JavaScript is among the world’s most used programming languages. Without it, we’d be looking at pages that do nothing other than display images and text. While CSS may be what offers style to a website, JavaScript (JS) is what gives it life.

Needless to say, without this amazing language, businesses would be at a loss. In today’s world, companies depend on languages like this to interact with their customers.

JavaScript is what allows you to interact with the vast majority of webpages that you visit. Whether it’s filling out forms, scrolling through maps, or registering to an event, it’s most likely that JavaScript is what’s allowing you to do it. 

Using the human form metaphor we used when talking about both HTML and CSS, JavaScript is to do with our movements and how we interact with others – like when we reciprocate a handshake, wink, laugh or ask a question.

It is a scripting language, and its powers allow us to control multimedia. It lets us add some animation to our images, and it can update content automatically on a page.

JS in today’s workforce

It’s vitally important for all industries, especially that we are now in an age where data is power. While it’s not the JavaScript that holds all of this data, it is what allows it to be manipulated in the browser. It’s the language that creates the functions needed to interact with a company through its website.

Employees with these skills are in huge demand, and its importance can not be understated.

Learn JavaScript!

If you’ve been contemplating a change of career, software development is one of the most in-demand roles in the world. No matter what industry you’re looking at, there is a need for developers to build the technologies, websites, and more.

Having a skill like JavaScript under your belt is massively advantageous if you want to change career. Front-end developers are needed everywhere. Of course, what’s even better is having the skills to handle a full-stack. That means having skills in both front end and back end software development. HTML, CSS, and JavaScript make up much of the front end, while other languages and technologies, like Python, Flask, MongoDB, Django, and many others, assist in making up the backend.
