No. 98% of typescript specific syntax can be replaced with U+0020 SPACE to yield runnable JavaScript. The runtime semantics of the two languages are congruent. the same cannot be said for any other language im aware of.
I'm sorry but if you need a transpiler to get it to run in a browser, character replacability and runtime semantics don't matter. Typescript doesn't run in the browser, it's obviously a different language.
