Variables

var (
	EmailRX = regexp.MustCompile("^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$")
)

Declare a regular expression for sanity checking the format of email addresses (we'll use this later in the book). If you're interested, this regular expression pattern is taken from https://html.spec.whatwg.org/#valid-e-mail-address. Note: if you're reading this in PDF or EPUB format and cannot see the full pattern, please see the note further down the page.
