How to convert an Object {} to an Array [] of key-value pairs in JavaScript

Question

I want to convert an object like this:

{\"1\":5,\"2\":7,\"3\":0,\"4\":0,\"5\":0,\"6\":0,\"7\":0,\"8\":0,\"9\":0,\"10\":0,\"11\":0,\"12\":0}

You can use Object.values([]), you might need this polyfill if you don't already:

const objectToValuesPolyfill = (object) => {
  return Object.keys(object).map(key => object[key]);
};
Object.values = Object.values || objectToValuesPolyfill;

Then you can just do:

var object = {1: 'hello', 2: 'world'};
var array = Object.values(object);

Just remember that arrays in js can only use numerical keys so if you used something else in the object then those will become `0,1,2...x``

It can be useful to remove duplicates for example if you have a unique key.

var obj = {};
object[uniqueKey] = '...';
