Converting Object to Array using ES6 features

Question

Given a javascript object, how can I convert it to an array in ECMAScript-6 ?

For example, given:

 var inputObj = {a:'foo', b:[1,2,3], c:null, z:55}; 

The expected output would be:

 ['foo', [1,2,3], null, 55] 

The order of the elements in the result is not important to me.

Answer 1

Use (ES5) Array::map over the keys with an arrow function (for short syntax only, not functionality):

let arr = Object.keys(obj).map((k) => obj[k]) 

---

True ES6 style would be to write a generator, and convert that iterable into an array:

function* values(obj) {     for (let prop of Object.keys(obj)) // own properties, you might use                                        // for (let prop in obj)         yield obj[prop]; } let arr = Array.from(values(obj)); 

Regrettably, no object iterator has made it into the ES6 natives.

Answer 2

just use Object.values

Object.values(inputObj); // => ['foo', [1,2,3], null, 55]
