Stuck on If statement.

I can't figure out why I'm stuck on this stupid little thing, I've tried ten different versions of code?

script.js 
const isAdmin = true;
const isStudent = false;
if ( isAdmin === 'true') {
message = 'Welcome admin';
}

Hi terry okey ! So the problem here is that you're testing to see if isAdmin is evaluating to the STRING 'true'. You want it to test for boolean value true, NOT the string "true". Try removing the quotation marks around the word true in your if statement and it should work ok.

Oh wow, I completely forgot. A boolean would never have quotes. Wow good lesson to learn.

I am also stuck on this challenge...not sure why this is incorrect?

const isAdmin = true; const isStudent = false; let message;

if ( isAdmin ) { message = 'Welcome admin.'; }

In my case I had erroneously added the single quotes to the statement. Anytime you add single quotes in javascript it means that it is a string. I was supposed to be testing for a boolean value, which is written without quotes and can only be evaluated as yes or no. But in this case, I was not getting yes or no because on the third line I put quotes around the word "true". Anything in quotes can never be evaluated as a boolean, only as a string.

In your case I'm not sure, but it looks to me like you have two statements on one line with a semicolon in between. I believe javascript always ends a line when it hits the semicolon. I think javascript is seeing the semicolon after your word true, and skipping to the next line. I think if you put the Const isStudent etc on the next line down your code will work?
