  Hey there,

  Here's the fix to your regular expression:

  const mailFormat = /^[a-zA-Z0-9._]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*\.[a-zA-Z]{2,}$/;
  

  The difference is that now it includes \.[a-zA-Z]{2,} at the end

  This ensures that the domain extension consists of at least two alphabetic characters. As a result, only email addresses with a valid domain extension like ".com", ".net", or ".org" will be considered valid.

  Also since it's a submit button you could consider using the submit event instead of the click event.

  Cheers

  @souravs97 Here's a breakdown:

  (?:) - Non-capturing group: allows grouping of multiple elements without capturing them as separate groups.

  . - matches any character except a newline character. It can match letters, digits, symbols, or whitespace.

  [a-zA-Z0-9-]+ - Character class: matches any uppercase letter (A-Z), lowercase letter (a-z), digit (0-9), or hyphen (-). The + quantifier specifies that the preceding character class should occur one or more times.

  • • Zero or more occurrences: It allows for optional repetition.

  Putting it all together, (?:.[a-zA-Z0-9-]+)* matches any character followed by a sequence of one or more alphanumeric characters or hyphens. This sequence can repeat zero or more times.

  • Use this regex

  const mailFormat =
    /^(([^<>()[\]\.,;:\s@\"]+(\.[^<>()[\]\.,;:\s@\"]+)*)|(\".+\"))@(([^<>()[\]\.,;:\s@\"]+\.)+[^<>()[\]\.,;:\s@\"]{2,})$/i;
