Javascript in many cases runs on v8 which is a just in time compiler. Just in time compilers provide substantial performance benefits for lines of code executed multiple times. Perhaps v8 team (google) doesn't support typescript (microsoft). https://softwareengineering.stackexchange.com/questions/2754...

No one executes TypeScript directly... It's a language that compiles to JS, which can then be run using V8 among others.
