A couple of months back, I've started posting colorful JavaScript code snippets that you can use to check your JS skills on my blog. Every problem has the correct answer and explanation. But I strongly suggest you first try to solve it yourself.
As an experiment, I'm going to post a new JS Interview Question every day here on hashnode.
Follow, like, comment if you're interested in learning about the common interview questions that Junior devs almost always fail.
