It is weird to me to see the loop breaking it in the if statement, especially since you are doing a additional if for every iteration of the loop.

could this not just be done as the standard

if ( .. ) {
  found = true; 
  break;
}

Or even better: use Array.prototype.some. But I'd rather do that in a different PR.
