Getting Started With JSX and HTML in JavaScript

For one of my personal projects, I found myself writing a lot of verbose vanilla javascript to create DOM elements, append text, add classes, attributes and event listeners — my code got really messy fast like this:

It turns out incorporating HTML in your javascript code with JSX is quite simple.

For those who don’t know about JSX, it’s code that looks like HTML that you write in your javascript code to create HTML elements.

To use JSX you need to use a transpiler like babel in your project. If you haven’t used babel, I highly recommend you learn about it, as it powers so much of the modern javascript code that developers write today.

The previous image was simple, and some of you might still not see the value of using JSX over creating DOM elements in vanilla javascript. But as your codebase grows, complexity grows and having a tool like JSX to abstract things away can make ourlives as developers easier.

You can download very small example app created by opening your terminal and running these commands on your machine:
