But I don't understand why the second half of the regular expression

@([-a-z0-9]+\.)+[a-z]{2,}/";

why is it able to detect repeated sections of the email address after
"@" that are separated by periods? like "@email.alaska.com" . It
looks to me like it's only looking for one example of that pattern.
Does the "()" allow an unlimited number of patterns to pass?

No, but the following '+' does.
