JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops For Loops

Why not ++?

The ++ operator is much simpler than += and works in Javascript, I was hoping to get some clarification on why the instructor in this video is still using +=, particularly in a for loop where ++ is the norm afaik.

I've noticed it before but figured it would be taught at some point, I was just curious if there was a particular reason it wasn't being used.

I would use ++ to increase by 1 and += if you need to increase by more than 1 or if adding on to strings or objects etc.

Maybe they're doing it in your course to make it more explicitly clear?

That seems like a very believable answer Emily.

I am not sure which is actually the norm but, I believe this is taught at some point. I certainly use the ++ when at all possible inside for loops and outside on some occasions.
