I get the bummer alert, but I believe I did everything the way it was supposed to. Correct me if im wrong please!
const isAdmin = true;
const isStudent = false;
let message;
if (isAdmin){
let message = "Welcome admin.";
}

6,145 PointsAlright! thank you both for helping me out! On another matter, why removing the let makes it work? Is it because trying to assign the value to the variable using let would be like creating a new one? Sorry if I'm being silly here.

statement defines the variable with script-level scope. When you use let message = "Welcome admin.";
inside the if statement, you are declaring a new variable that only exists until the if statement is done, so if you tried to use the message variable afterwards (like with a console.log(message);
, the output would be undefined
rather than the expected message because the first message variable is initialized to undefined
when it is created, and then it is never updated. By removing the let
from inside the conditional, you are then assigning the value "Welcome admin." to the variable message that you created with the let message;
statement.
