Having problems getting this prototype function to work to format a number into a phone number format.

Number.prototype.toPhone = function () {
    myStr=this.toString().replace(/(\d{3})(\d{3})(\d{4})/, '$1-$2-$3');
    return myStr
}

So how come you can't execute it like this

var myNumber=1111111111;

console.log(myNumber.toPhone);

Add parentheses :
var myNumber=1111111111;

console.log(myNumber.toPhone());
