TypeScript is a superset of JavaScript. It means any valid JavaScript is also valid TypeScript.

This is backwards. JS is superset and all TS compiles to valid JS.

The vast majority of JS does not translate to Typescript as the JS is untyped.

You don’t necessarily need to believe me but please double check your claims before you spread misinformation

To be a superset, all elements of the subset must be contained within the superset.

TypeScript is a superset of JavaScript as valid JS code(just with everything implicitly the any type) is valid TS code.

Oh yeah if you add some sort of typing to the Javascript, sure.
