Should I play Challenges after third lesson?

Question

As in Question, I just started JavaScript tutorial. So should I play Challenge mode or will I be at disadvantage until I complete all lessons?

Answer 1

I'd advise all lessons before challenge really, just to make sure that you understand all the concepts first.

That being said, theres nothing stopping you from trying it out and seeing how you do, the challenges, for the most part, rely on Math-based problems, so the challenge is more of a math quiz than it is a Javascript test. But it'll still help you learn :)
