JavaScript How to use custom created methods of a string prototype?

I created my own method which basically capitalizes the first alphabet of every word in a string.

However, I am getting this Uncaught TypeError: Cannot read property 'split' of undefined error. Where am I wrong?

String.prototype.toCapitalize = (str) => {
  let splits = str.split(" ");
  let capitalize = '';
  splits.forEach((el) => {
    let result = el.charAt(0).toUpperCase() + el.substr(1, el.length).toLowerCase();
    capitalize = capitalize + ' ' + result;
  });
  return capitalize;
}
let h = 'its a beautiful weather';
h.toCapitalize();
Answer:1

How did you think that the first argument is the string? It is supposed to be this. Replacing str with this and works:

String.prototype.toCapitalize = function () {
  let splits = this.split(" ");
  let capitalize = '';
  splits.forEach((el) => {
    let result = el.charAt(0).toUpperCase() + el.substr(1, el.length).toLowerCase();
    capitalize = capitalize + ' ' + result;
  });
  return capitalize;
}
let h = 'its a beautiful weather';
console.log(h.toCapitalize());
Answer:2
