Sorry for the poor choice of word on my part, I admit I was using "disingenuous" incorrectly there. I just thought the description of sublime/emacs/vim having "great" support for TypeScript might give someone the impression that something beyond syntax highlighting was supported.

I don't doubt that it's more work to support more than syntax highlighting, but that doesn't change the fact that the support in those editors is sub-par when compared with lots of other languages. For example I can install SublimeLinter and have basic error reporting for python code, or SublimeJEDI and have code completion and go to definition.
