Earlier quoted context omitted.
Microsoft has an extraordinary amount of in-house talent when it comes to IDEs and performance, and it shows in VSCode. The difference in responsiveness between the two editors is stark and it's a primary reason I never use Atom anymore (though the increasingly sophisticated intellisense and integrated CLI tools is what's kept me in VSCode).
Idk but I remember reading somewhere that VSCode is written by a 5 man team?
Isn't Sublime Text one guy..?
