"use strict";

function findNames(text, name, start = 0) {
  const hits = [];
  const hit = text.indexOf(name, start);
  const end = hit + name.length;
  if (hit !== -1) {
    hits.push(text.substring(start, end));
    findNames(text, name, end)
      .forEach(result =>
        hits.push(result));
  }
  return hits;
}

const text = "Valentine, Valentine, Valentine, Valentine, Valentine, Valentine.";

const myName = "Valentine";

console.log(findNames(text, myName));
