Not a Good First Choice for Scripting Language

Typescript is not a good choice for scripting language for one simple reason: There is no support for simple multi threading.

There are worker threads but they require communication complexity, which isn't what you want to be doing when writing a simple script, that ended up needing some parallelization.

So unless you are already a TS/JS pro, picking TypeScript language as a scripting language is not a good idea.
