This is why I continued to use sublime text all the way up to capitulating to TypeScript. Code was slower because of all the intellisense. I've had Code freeze on me a few times. Something that I don't have happen in Sublime or Vim. If you have a lot of RAM and work on a current mainstream OS it may seem smooth, but it's still using 400mb of RAM. May as well use Eclipse or WebStorm FWIW. That said I'm using VSCode now too, but things can always be better :).
