Hello, friends!
I’m currently doing some advanced algorithm and I’m stuck with my solution. FCC suggests regex to solve this exercise, but I tried to use regular if statements and almost everything works, but some cases keep returning wrong answers. I really don’t get what’s the difference and why the code is not working properly.
function telephoneCheck(str) {
// Good luck!
var arr = str.split("");
var newArr = [];
arr.forEach(function(number){
if (isNaN(number) === false && number !== " "){
newArr.push(number);
}
});
if (newArr.length === 10){
return true;
} else if (newArr.length === 11) {
if (newArr[0] == 1) {
return true;
} else {
return false;
}
} else {
return false;
}
}
telephoneCheck("1 555-555-5555");
As always, thanks a lot for your attention and help
