JavaScript - Sort objects by value but return key

Question

I have an Object like this:

object = {A: 15, B: 30, C: 22}

So I'm sorting it using its values. For that, I have this function:

object = { A: 15, B: 30, C: 22 } function sortObjsValues(obj) { return Object.values(obj).sort((a, b) => { if (a > b) { return -1; } else if (a < b) { return 1; } else { return 0; } }); } console.log(sortObjsValues(object)); // => returns 30,22,15

Is there a way to return its keys instead of its values, keeping sorting by its values? The final result would be B,C,A

You could get entries from the object, sort by value descending and map the keys.

const object = { A: 15, B: 30, C: 22 }, getSortedKeys = o => Object .entries(o) .sort((a, b) => b[1] - a[1]) .map(([k]) => k); console.log(getSortedKeys(object));

Just sort the keys by the value.

const object = { A: 15, B: 30, C: 22 }; console.log(Object.keys(object).sort((a, b) => object[b] - object[a]));
