Should I bother with style50?

Have submitted PSets of Week 0 and 1 so far with perfect check50 scores but I didn't really understand how style50 worked so I didn't really do anything about it. But as far as I know it wants to remove all blank space and make the program compact.

I actually like to style my code a certain way for example: if (a == b) instead of how style50 recommends it if (a==b)

First one is more readable for me so I add spaces even though they are not necessary

I don't understand style50 in other parts where it highlights red

Should I really bother with style50 and resubmit the PSets? Can someone explain how it works as well?
