Exercises to learn javascript

Depends on your experience really. If you're a beginner, you don't really want exercises but rather 'projects' that you can complete so you're familiar with the whole cycle and the syntax. But learning the syntax isn't really the challenge in Javascript. The challenge comes from learning the libraries, frameworks like React, and data structures. The "exercises" as you put it, are often more like logic puzzles that need to be solved in Javascript. This is useful for people who already are familiar with Javascript syntax and want to get better at coming up with algorithms on the spot. A beginner would immediately get stuck and learn nothing even if the solution was provided. So with all that said, and assuming you're new to Javascript, I would recommend following the free Scrimba tutorial. It's 7 hours of material and you work in an integrated environment which means you can pause the instructor's video and immediately take over the code that's been written. It's a fun way to start: https://scrimba.com/learn/learnjavascript More on reddit.com

You could try codewars. I wouldn't look at the solutions too much. Often times they're clever one liners that aren't really that readable, but it could definitely help you learn.
