change object with angular foreach loop to array

Question

This is my object {angry: "ok", sad: "nw", fire: "ok", happy: "nw","something":"good"}

I want to change this object to something like this:

val[nw][0]="sad" val[nw][1]="happy" val[ok][0]="angry" val[ok][1]="fire" val[good][0]="something" 

how can i do that?

Answer 1

You could iterate the keys and build a new object upon.

var object = { angry: "ok", sad: "nw", fire: "ok", happy: "nw", something: "good" }, result = {}; Object.keys(object).forEach(function (k) { result[object[k]] = result[object[k]] || []; result[object[k]].push(k); }); console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
