Javascript phone number to letters

Question

I want that it print a phonenumber in letters.

var getal = new Array();
getal[0] = 'nul';
getal[1] = 'een';
getal[2] = 'twee';
getal[3] = 'drie';
getal[4] = 'vier';
getal[5] = 'vijf';
getal[6] = 'zes';
getal[7] = 'zeven';
getal[8] = 'acht';
getal[9] = 'negen';
telefoonnummer = prompt("What is your phone number?");
document.write("<br>" + telefoonnummer);

When you type in '12345678' I want that it prints 'one two three four five six seven eight'

break the phonenumber and replace each characters with equivalent word

       var getal = ['nul','een','twee','drie','vier','vijf','zes','zeven','acht','negen'];

        telefoonnummer = prompt("What is your phone number?");
        telefoonnummerwords = telefoonnummer.split("").map(x=>getal[x]).join(" "); 
        document.write("<br>" + telefoonnummerwords);

Create an object instead of an array. Once the user enters an input split the input and then use map to iterate over it. On each iteration use the element to get relevant value from the object. Then use join with delimiter white space to create a string

var getal = {
  0: 'nul',
  1: 'een',
  2: 'twee',
  3: 'drie',
  4: 'vier',
  5: 'vijf',
  6: 'zes',
  7: 'zeven',
  8: 'acht',
  9: 'negen'
}
let telefoonnummer = prompt("What is your phone number?");
let k = telefoonnummer.trim().split('').map(function(item) {
  return getal[item]
}).join(' ');
document.write("<br>" + k);
