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

— Working version

— Still doesn't make much sense to actually store the same value to the array this many times though

— Why not just keep hits a number?

— And just + 1 everytime you get a hit?

const findNames = (text, name, start = 0, hits = []) =>
  (hit => hit === -1
    ? hits
    : (end =>
      (hits.push(text.substring(hit, end)),
        findNames(text, name, end, hits))
    )(hit + name.length)
  )(text.indexOf(name, start));
