Is JavaScript plus static type checking and a few other syntax enhancements. It is much easier to maintain software with static type checking. The typescript compiler outputs JavaScript

Debatable

It’s a superset of JavaScript. The big add is static typing, reducing the chance of runtime type errors. It compiles to vanilla JavaScript for distribution. Other new features include enums, interfaces, and generics for more type safety.

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?

[–] mercano@lemmy.world 3 points 2 months ago

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.

It’s basically just a programming language based on and inclusive of JavaScript, but with extra features.

Javascript but types ( I haven't used it)
