Tell us what’s happening:
When I look in hints section and try the Intermediate solution for this challenge given in it, it wouldn’t pass the test.

Your code so far


function telephoneCheck(str) {
  var re = /^((\+?1\s*([.-]\s*)?)?(\(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*\)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*([.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*([.-]\s*)?([0-9]{4})$/;
  return re.test(str);
}
telephoneCheck("555-555-5555");

Is it just my device or all where it won’t work ?

No, it fails these two tests for me as well.

telephoneCheck(“555-5555”) should return false.
telephoneCheck(“5555555”) should return false.

I guess we need to update the guide.

Yeah, same those tests are being held with me too.
