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

With lodash, in addition to the answer provided above, you can also have the key in the output array.

Without the object keys in the output array

for:

const array = _.values(obj);

If obj is the following:

{ “art”: { id: 1,  title: “aaaa” }, “fiction”: { id: 22,  title: “7777”} }

Then array will be:

[ { id: 1, title: “aaaa” }, { id: 22, title: “7777” } ]

With the object keys in the output array

If you write instead ('genre' is a string that you choose):

const array= _.map(obj, (val, id) => {
    return { ...val, genre: key };
  });

You will get:

[ 
  { id: 1, title: “aaaa” , genre: “art”}, 
  { id: 22, title: “7777”, genre: “fiction” }
]
