Email verification function with Regex explanation

function isValidEmail(mail) {
    const email = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
    /* reminder to self:
        / -> /  = here is Regex
        ^       = start of string
        []      = character set (\s = space)
        ^ in [] = must not contain
        +       = string must contain
        So, above test is 'string must not contain space or @ before the @ nor should it have space or @ before the . nor should it have space or @ after the .'

    return email.test(mail);
