r.d.fred-2021@hull.ac.uk (for student)
r.d.fred@hull.ac.uk (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 ?
Try the following regex
const str1 = "r.d.fred-2021@hull.ac.uk";
const str2 = "r.d.fred@hull.ac.uk";
const regex = /[0-9]{4}/;
console.log('str1 has year -- ', regex.test(str1));
console.log('str2 has year -- ', regex.test(str2));
