    split return array, so catch your desire result based on index of that array.

    Example:

    let array = [
  'age 19 - Donna',
  'age 20 - James'
];

let getNumber = [] //19 and 20
let getName = [] // Donna and James

for (let i = 0; i < array.length; i++) {
  let val = array[i];
  getNumber[i] = val.split(" ")[1];
  getName[i] = val.split(" ")[3];
}

document.getElementById("demo").innerHTML = getNumber;
document.getElementById("demo2").innerHTML = getName;
    <div id="demo"></div>
<div id="demo2"></div>

    Using match with a a regular expression might be a little simpler.

    const demo = document.getElementById('demo');
const demo2 = document.getElementById('demo2');

const array = [
  'age 19 - Donna',
  'age 20 - James'
];

const getNumber = [];
const getName= [];

// Create a regex that picks up a group of numbers
// and a group of letters
const re = /(d+) - ([a-zA-Z]+)/;

for (let str of array) {

  // `match` on the string with the regex,
  // destructuring the number from the first group
  // and the name from the second group
  const [ , number, name ] = str.match(re);

  // Push the values into the arrays
  getNumber.push(number);
  getName.push(name);
}

demo.textContent = getNumber;
demo2.textContent = getName;
    <div id="demo"></div>
<div id="demo2"></div>
