Is there a way to use algorithm challenges more efficiently?

Programming JavaScript

Hi, there!

:space_invader: :space_invader: :space_invader:

I’ve survived through most of the JS algorithm challenges.
I’ve always derived my own solution.
As I’m new to coding - my solutions (I assume more often than not) are… let’s say… sub-optimal (crooked but working).

Is there a way to use these challenges not only to the point where “at least it works” , but also to start making my code more efficient and concise? Any tricks?

Thanks a lot for your attention!
