MSVC is a C++ compiler toolchain and it does not contain any JavaScript. You're thinking of VSCode, probably, but your comment was an off-topic rant either way.
Also my comment was a single sentence with a single fact so it can't be a rant.
It can and does refer to the IDE first. I'll prove it to your by showing that it's the first result of a search.

It’s OK to say you were wrong. You don’t have to be angry online. I promise!
Seems like projection. Since it's ok to be wrong I guess you'll reply with an apology.
