> TypeScript compiler essentially treats types as a lint

Sorry, I think you've been swindled.

The Typescript compiler is made by Miscrosoft and is called tsc. It very much heeds the type annotations, and very much rejects ill-typed programs. An LSP based on it does the same in an editor. Also tsc supports refinement types via flow control analysis and a bunch of other static correctness checks.

Deno, bun, swc are not true compilers like tsc, they don't do much correctness checking at all. They discard al the type info, and then operate on pure JS (modules conversion, minification, etc).
