    Genuine question: is it really a superset if it’s not still valid javascript? Isn’t it more of an abstraction layer on top of javascript?

      Superset means all valid JavaScript is also valid Typescript. (At least, so long as you don’t have compiler setting on that requires all variables to have a type declared.)

      In practice people don’t use Typescript as a superset since they have stricter compiler settings, which would make valid JavaScript fail to compile.
