Not free though. You can also add VSCode to the list. It's faster than Atom but slower than sublime (Which is also not free). Also it may be good to start with a plain editor than a fancy one like JetBrains and later purchase a fancy IDE when you have learned the inner workings to improve your productivity.

I wasn't aware Sublime has a trial period thus I included on the list.

I edited the post a bit to accept non-free editors as well.
