Filtering specific values on json array and create another array

Question

How can i create another array by filtering one json array and include just the values pairs of a specific key?

Example (Filtering Value Pairs of Number Keys):

Array:

{ Name: 'abcd', Number: '1234' },
{ Name: 'efgh', Number: '5678' }
]````

Result Array:


````var filteredarray = ['1234','5678'];````

Thanks!

Use map. const array2 = array1.map(function(item) { return item.Number }) — Andrei Panturu, Nov 04 '19 at 11:55

const a = [
 { Name: 'abcd', Number: '1234' },
 { Name: 'efgh', Number: '5678' }
]

function getNumbers(){
  return a.map(item => item.Number);
}

getNumbers();
