r/learnjavascript on Reddit: What is a good website to practice JavaScript?
April 8, 2024 -
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?
