javascript/jquery 中是否有任何内置的 function 来过滤 email 就像 php 的 function (,filter_var($variablePassed, FILTER_VALIDATE_EMAIL))

Question

// check if e-mail address is well-formed
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    $emailErr = "Invalid email format"; 
}

This code is filtering the email provided by the user.

My question is is there any built in function in javascript/jquery like this php built in function. Regex is doing it but some times regex stop working.I do not know why. My question is not so good but my mind force me to ask so i can feel good.I cannot sleep without answer.

There is no built-in but 3rd-party library provided on NPM.
