Say I have an array of objects:

[
  {
    'prop1': 'hello world',
    'prop2': false
  },
  {
    'prop1': 'asdf asdf',
    'prop2': true
  },
  {
    'prop1': 'bob ross',
    'prop2': false
  }
]

And now I want to create a new array that just lists one of the properties, for example:

createArrayFromProperties(array, item.prop1);

↓ Output ↓

['hello world', 'asdf asdf', 'bob ross']

Is this possible to do with a built in JS method, or do I have to use a loop?

`Array.prototype.map()` i would say – Redu Aug 07 '16 at 19:38
`arr.map(el => el.prop1)` – Ram Aug 07 '16 at 19:38

Please note the code snippet uses an arrow function, if you are not using an ES6 transpiler, use a regular function instead, as the accepted answer of the duplicate question. – Ram Aug 07 '16 at 19:43
