Tell us what’s happening:

it keeps logging out undefined and i am not sure of what to do

Your code so far

function maskEmail(email) {
  let first = email.slice(0, 1);
  let last = email.slice(domain - 1, domain);
  let mid = email.indexof("@");
  let domain = email.slice(mid);
  let stars = "*".repeat(domain - 2);

  return first + stars + last + domain;
}

let email = "joe36@gmail.com";
console.log(email.maskEmail);

Could you explain what these lines are supposed to do?

3

The email variable is a sample data meant to test the function and the second line in there is supposed to log the end product of the email being passed through the function.

4

Does email.maskEmail pass the email variable to the function?

5

No it does not. Let me revise and make a few touches

6

I thought changing it to this would produce the intended result but it didn’t

let email = "joe36@gmail.com";
console.log(maskEmail(email));

7

What does it produce instead?

8 
ReferenceError: can't access lexical declaration 'domain' before initialization

I think i only declared the domain variable later but prior to that i had already tried using it in the upper lines of the code

Thank you very much. I have been able to complete it. I think the main roadblock was that I used variables without paying attention to their datatypes.
