Javascript iterate Json Array to get values

Question

I have a below JavaScript

var arr = [];
arr.push({0:\'Zero\'});
arr.push({1:\'One\'});
console.log(Object.keys(arr));
console.log(Object.values(arr)); //Not          


        

Answer 1

It's because arr is an array, not an object. You should use map like so:

var arr = [];
arr.push({0: 'Zero'})
arr.push({1: 'One'})
console.log(arr.map(e => Object.keys(e)).flat(1));
console.log(arr.map(e => Object.values(e)).flat(1));

I used flat to make the array flat, instead of it being nested.
