What Are the Different Types Of Coding?

It can be tricky to know where to start when learning to code, because there are so many different programming languages. Here’s a quick run-down of five of the main types you’ll come across when exploring the best online coding courses listed above, to help you know which ones you might want to learn.


HTML and CSS are computer languages that are a standard requirement for all web developers. HTML tells browsers how to read webpages – for example, HTML code signals to your browser what’s a paragraph, what’s a button, and so on.

CSS then tells the browser how these elements should look. This affects the color, spacing, and general styling of the elements on a webpage.

2. JavaScript

JavaScript is what makes websites interactive – this is the magic behind any elements on a site that move or change without you doing anything to them!

Because of this, JavaScript is often used alongside HTML and CSS, because they’re all frontend coding languages – that is, they all affect how things look and behave on a website from a user’s point of view. Other languages apply to the “backend” of your site, meaning they control things that happen behind the scenes. We’ll look at these next!

Good to know… Don’t confuse JavaScript and Java – they sound similar, but are actually different things!

3. Python

Python is ideal for processing data, making it popular with biology and math students, as well as researchers. You’ll want to learn Python if you’re creating a site that analyzes a lot of text or data sets.

4. Java

Java is a programming language that’s usually used for embedding media. Java is especially useful because you can take the code and use it across multiple platforms. You don’t even need to customize it to move it from a PC to mobile!

5. C and C++

These are both separate languages, but for the sake of speed, we’ll quickly walk you through the differences between C and C++.

C is a pretty low-level language that’s usually used for communication between computer hardwares. It’s commonly taught online and is pretty popular, so you’ll likely spot it time and time again.

C++ is an improvement on C because it organizes information in a much better way – it stores information in bundles, making it easier to use. This makes it particularly useful for large, complex systems.
