[email protected] (for student)
[email protected]      (for teacher)

I want to assign roles as a student if it includes year otherwise teacher during user registration.

what would be the regex expression for this or any other optimal solution ?

CodePudding user response：

Try the following regex

const str1 = "[email protected]";
const str2 = "[email protected]";

const regex = /[0-9]{4}/;

console.log('str1 has year -- ', regex.test(str1));
console.log('str2 has year -- ', regex.test(str2));
