  let sliceEmail = oldEmail.slice(indexEmail-1);   //p@example.com
  let sliceFirstLetter = oldEmail.slice(0,1);
  let star = "*".repeat(indexEmail-2);

  return console.log(sliceFirstLetter+star+sliceEmail);
  
}
let email = "johnappleseed@email.com";

Welcome to the forum @fauzyfath!

Please wrap the function calls you’re using to test your code in console.log(). That is the standard way to see what your function is returning in the console.

let email = "johnappleseed@email.com";
console.log(maskEmail(email));
email = "apple.pie@example.com";
console.log(maskEmail(email));

You should now be seeing undefined in addition to your email mask.

What does it mean when a function returns undefined?

Happy coding!
