r/javascript on Reddit: Good free text-editors for javascript

December 11, 2016 -

I'm starting to learn JavaScript and I'm looking for a good and free texteditor. I use notepad++ at the moment, which I think is fine for writing HTML/CSS. But for me it's quite inconvenient for writing js because it doesn't give text color very often. And when I make a mistake it's very hard to find which part of the code provides the error. On codecademy.com they have a really nice editor, but I don't think it's free to download. So if you have a good alternative please let me know.

P.S. I don't know if document.write is just for notepad and notepad++ or for all editors, because I've seen some where you put in console.log or whatever.
