Create an object from a given array

Javascript

Use this function to convert objects to an array of objects

function objectFromArray(arr, key = 'id') {
  if (arr && arr.length) {
    return arr.reduce((v, i) => {
      v[i[key]] = i;
      return v;
    }, {});
  }
  return {};
}

Usage example:

const people = [
  {
    "id": "123",
    "name": "John"
  }
];

console.log(objectFromArray(people)); // prints { "123": { "id": "123", "name": "John" } }
