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}

Answer 1

Yet another solution if Object.entries won't work for you.

const obj = {
      '1': 29,
      '2': 42
    };
const arr = Array.from(Object.keys(obj), k=>[`${k}`, obj[k]]);
console.log(arr);
