JS Code Regex to verify Email

Hi,

Does anyone have some JavaScript that can verify a valid email address in the code module?

I have the following - but I cant find the right way of performing the test, I’m not a programmer but I cant see why this isn't working? Any help much appreciated. At the moment it seems to pass everything through.

if(inputData.eMail == null){
 return{ rv: ""}
}
else {
  const myEmail = inputData.eMail.replace(/\s+/g, '') // remove all whitespace from string
  const RegExpConst =  /(?:[a-z0-9!#$%&\'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])/

  if(myEmail.matchAll(RegExpConst)){
     return {rv: myEmail}
  }
  else return {rv: ""}
}
