Build a Boolean Check Function

JavaScript
1

I got tests 1, 2, 3 correct. But the rests of the tests for arguments of any other value I can’t pass. Can someone please help?

function booWho(argument) {

if (argument === true || argument === false) {

console.log(true);

} else {console.log(false);}

return true || false;

}

console.log(booWho(true));

console.log(booWho(false));

console.log(booWho([1, 2, 3]));

console.log(booWho([].slice));

console.log(booWho({ “a”: 1 }));

console.log(booWho(1));

console.log(booWho(NaN));

console.log(booWho(“a”));

console.log(booWho(“true”));

console.log(booWho(“false”));

Welcome to the forum @chibilou0x !

Hopefully, this MDN reference will help you:

I still don’t get it. I don’t know how to link the MDN ‘Creating false values’ examples to this practice.

I am honestly not sure what else I need to add to my function block in order to prove that the other arguments are false.

This is probably a more helpful MDN link:

this is what your function is returning, which means it always return the same thing
