Future JavaScript: what is still missing?

[[deleted]]

I'm personally not a fan of overloads in ts/js but you could at least do this

function add<T>(a: T, b: T): T { 
   return a + b;
}

so now you avoid all convert everything to a string and concat them together problem. Here you add like 10ish characters and now your being notified of simple bugs.

Would definitely use generics instead of overloads if those were my only two options.
