Validate email address

Validate an email in JavaScript using regular expression.

Remember that JavaScript might be disabled in your browser and that server-side validation is always required.

Shortcut: email.isvalid

const isValid = String(email)
  .toLowerCase()
  .match(
  /^(([^<>()[\]\\.,;:\s@"]+(\.[^<>()[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
