Email Validation (React Native). Returning the result as 'invalid' for all the entries

Question

I am trying to validate a users email, by checking it against an expression. But the result i am getting is invalid for all the entries.

UPDATED CODE

Answer 1

I've created a Helper class and doing like this:

export default class Helper {

     static isEmailValid(email) {
        let reg = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
        return reg.test(email) == 0;
   }
}

Call this method by:

if (Helper.isEmailValid(this.state.emailText)) {
    console.log("Email is correct");
} else {
    console.log("Email is not correct");
}
