How to create custom find method?

Question

I'm trying to create custom find method using Array.prototype, I tried a lot of way but i just couldn't break the loop for the first match:

let arr = ["Bill", "Russel", "John", "Tom", "Eduard", "Alien", "Till"];
Array.prototype.myFind = function (callback) {
  for (let i = 0; i < this.length; i++) {
    callback(this[i], i, this);
  }
};
arr.myFind((element, index, array) => {
  if (element[0] === "T") {
    console.log(`This is ${element} in index of ${index} in array ${array}`);
  }
});
