I've been using VSCode for TS (nothing else though). Do you mind elaborating on why Webstorm is on a different level? Genuinely curious. I really like VSCode, but I have my complaints (mainly, it's a little slow on my MBA)
I LOVE the tooling in webstorm, but the it just eats up all my ram and pegs out the CPU on my 2011 MBP. And if it's trying to index a large project, I just take a break because it renders my machine almost unusable.
... One time I tried to do "setX(y);" in one of my programs, and it warned me that I probably didn't mean to do that. Amazing.
If you have less than 8GB of RAM though, you probably don't want to use it for large projects.
