Best way to sort by key or value? about hashmap HOT 6 CLOSED

What you mean sort? It's not an ordered collection.
Are you referring to the order you get them items when you call forEach()?

If so you could do something like:

map.keys().sort().forEach(function(key) {
  var value = map.get(key);
  // ...
});

from hashmap.

that'll work... thanks!

so the sort on keys works well... but... how would you go about sorting on value?

from hashmap.

This?

map.values().sort().forEach(function(value) {
  // ...
});

from hashmap.

Right, but then how to retrieve the key? On this example:

joe : 10
alice : 50
paul : 2
phil : 10

I can sort the values and get 50, 10, 10, 2... but then how do i get back to the keys so i can display something like:

alice : 50
joe : 10
phil : 10
paul 2

Thanks!

Well, for start, there's no point in using using HashMap for string keys. You can use a plain object for that.
At this point, if you wish to continue this way, I'd say you should rather modify hashmap code to suit your needs.

You can solve it by asking for the keys and values and making some sort of external collection but at that point, why would you even be using hashmap.
