Write a function that converts number to text, Passing an int number should return array of text number eg 23498643 => [two, three, four, nine, eight, six, four, three] 40263645 => [four, zero, two, six, three, six, four, four, five] You5:43 PM Update the function to group the numbers by 2s 23498643 => [twenty-three, fourty-nine, eighty-six, fou…

  tens: ['twenty', 'thirty', 'fourty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety']
