  • what have you tried? try using [Array.prototype.map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) or [flatMap](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/flatMap) – AZ_ Aug 05 '19 at 10:09
  • var newArray = oldArray.map(innerArray=>innerArray[0])) – nivendha Aug 05 '19 at 10:09

Use Array.flat():

const arr = [[{a:1}],[{a:2}],[{a:3}]];

const output = arr.flat();

console.log(output);

Simply flatten the array:

const arr = [[{a:1}],[{a:2}],[{a:3}]];
const flattened1 = [].concat(...arr); // With destructuring
const flattened2 = arr.flat(); // with Array.flat();
console.log(flattened1);
console.log(flattened2);

You can always use flatMap: arr.flatMap(x => x)
