 If we ever meet a word the same letter-sorted form again, then it would overwrite the previous value with the same key in the map. So we'll always have at maximum one word per letter-form.

 At the end `Array.from(map.values())` takes an iterable over map values (we don't need keys in the result) and returns an array of them.

 If we have a plain object, and we'd like to create a `Map` from it, then we can use built-in method [Object.entries(obj)](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/entries) that returns an array of key/value pairs for an object exactly in that format.

 Note the funny thing. The callback function passed in `forEach` has3 arguments: a `value`, then *the same value* `valueAgain`, and then the target object. Indeed, the same value appears in the arguments twice.

 That's for compatibility with `Map` where the callback passed `forEach` has three arguments. Looks a bit strange, for sure. But this may help to replace `Map` with `Set` in certain cases with ease, and vice versa.
