TS compiles to JS, so when you actually execute a script, you’re just starting Node, Deno, etc. with a JS file. Any of those are probably faster to start than Python. Deno in particular starts in around 15-60 milliseconds. Even if it has to compile the Typescript - which is a one-time operation if the script isn’t changing - it still typically starts in under 250ms.
