Type difference?

JavaScript

Tell us what’s happening:
So I got the answer and wrote practically the same solution as this one, but one thing I don’t understand is if it uses a ‘===’, how does it work equaling a string, “boolean”? true/false is a boolean value but “boolean” is a string. In my solution I used a ‘==’.
Your code so far


function booWho(bool) {
return typeof bool === "boolean";
}

booWho(null);

typeof gives you the string of the type so for a boolean value it returns 'boolean'
