How could i format my regex, to validate an email with multiple domains, like jane@student.edu.au?

i am using this regex

const emailRegex = new RegExp(/^[a-zA-Z0-9]+@[a-zA-Z0-9]+\.[A-Za-z]+$/);

but after i put .au, it considers it an incorrect email

>Solution :

maybe you can specify the number of characters ?

const emailRegex = new RegExp(/^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})+$/);

like so

const emailRegex = new RegExp(/^([a-zA-Z0-9_\-.]+)@([a-zA-Z0-9_\-.]+)\.([a-zA-Z]{2,5})+$/);

let matches = 'john.doe@domail.au'.match(emailRegex);

console.log(email);
