Iterating over an object keys, an array or a map?

  I would expect, given you have described an operation on 3 different data structures using different words, that it would also demand 3 different kinds of syntax/denotation no? Your own language requires as much. Why not JS?

    Well in python by example you use for x in myobject to iterate and that's it, no Object.entries(myobj) vs. mymap.entries , lua is even more consistent, ..

      It’s not uncommon in Python to iterate through dict.items() (or dict.keys()) which is basically the same thing.

      Hey what about map and comprehension? This is a language that claims to value "one way to do things"

  let obj = {a:1}, arr = [1], map = new Map().set("a",1); // Iterating over an object keys for (let x of Object.keys(obj)) {...} // an array for (let x of arr) {...} // or a map? for (let x of map) {...}
