What do I need to know before learning JavaScript?
JavaScript is fairly easy to pick up on, so you can jump in without prior knowledge. Still, it helps to have a basic understanding of fundamental programming concepts (which you can learn in our Code Foundations skill path). If you're learning JavaScript to build websites, you'll want to brush up on HTML and CSS first. HTML gives a website structure, CSS provides style, and JavaScript enables interactivity.

r/learnjavascript on Reddit: What is a good website to practice JavaScript?
December 25, 2023 -
I am looking for a website with lots of JavaScript exercises that I can practice the concepts that I am learning. I am not so much looking a site to teach me JavaScript as I have plenty of sources to learn already. I know that there are many different places like LeetCode or Codewars, but I am not sure how beginner friendly they are. I was using Edabit, and it was perfect for what I was looking for, but it is not free unfortunately, and my free trial has ended, and I am not in the position to pay for practicing JavaScript at the moment. Is there a free alternative for Edabit?
