Tell us what’s happening:
May have found a bug with one of the tests.
Using my regex expression:
^(?:(?:1?\s*(?:[-]\s*)?)?((\s*((\d{3})|\d{3})\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})$
on this site: https://www.regextester.com/17
The test: 5555555555
Was not passing. However, on fcc it passed the test no problem.
Your code so far

var regex1 = /^(?:(?:1?\s*(?:[-]\s*)?)?(\(\s*(\(\d{3}\)|\d{3})\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})$/;
console.log("str: " + str);
console.log(regex1.test(str));
return regex1.test(str);
}
console.clear();
telephoneCheck("555-six-5555");
