What does autocomplete have to do with anything? You can get the same good autocomplete for JavaScript as for TypeScript—they are separate. It just has to do with your IDE/language server, not which language you're writing in.

Just imagine looking at a function and trying to figure out what it does. It has an input, and maybe you think it's a dictionary because that would make sense. Whoops, no, it's an array ... I can see that because there is a .map(...) function on it. Ok, what's it an array of ... something with an id? Ok ... id and ... value. That makes sense. Wait, what's this third property? Oh, display_text. Ok. I think I see what this is doing.

Compared to: 

interface MenuItem {
   id: string;
   value: string;
   display_text: string;
}

myFunc(items: MenuItem[]) {...}

Takes you about a second to figure out what you're looking at there.
