javascript - How to convert key-value pair object into an array of values in ES6?

I'm developing a React application where I need to convert a key-value object like this:

{
  0: 'John',
  1: 'Tim',
  2: 'Matt'
};

To an array of just the values like this:

['John', 'Tim', 'Matt']

How do I accomplish this?

const obj = {
  0: 'John',
  1: 'Tim',
  2: 'Matt'
};

const arr = /* ??? */;

You could use Object.values.

The Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

var object = { 0: 'John', 1: 'Tim', 2: 'Matt' }, 
    array = Object.values(object);
    
console.log(array);
