object-iterable

Object Iterable

Create a new object containing the same properties (through assignment) of another object along with an @@iterator method can make use of the default iteration behavior (such as for-of) that built-in iterables like Array or Map have.

npm install --save object-iterable

Let's see an example

const larry = {
  name: 'Larry Johnson',
  alias: 'Grandmama',
  position: [
    'Power Forward',
    'Small Forward'
  ],
  weight: 250,
  height: {
    feet: 6,
    inches: 6
  },
  college: 'UNLV',
  draft: {
    team: 'Charlotte Hornets',
    year: 1991,
    pick: 1
  }
};
 
for (let val of larry) {
  console.log(val);
}
// Uncaught TypeError: larry[Symbol.iterator] is not a function

Oh nos!

But we can get through this.

Here an iterable new object is returned with all the same properties (which after use can optionally be kept or discarded).

import iterable from 'object-iterable';
 
const iterableLarry = iterable(larry);
 
for (let val of iterableLarry) {
  console.log(val);
}
// Larry Johnson
// Grandmama
// ["Power Forward","Small Forward"]
// 250
// {"feet":6,"inches":6}
// UNLV
// {"team":"Charlotte Hornets","year":1991,"pick":1}
 
console.log(larry === iterableLarry);
// false
