Answer 1

Look at checkCreatures() line 12, you should evaluate by using equality operator `==` rather than assignment operator `=`

return element.habitat == "ocean";

Answer 2

Will try that IPang

Answer 3

Thanks @Ipang ,it worked

Answer 4

steve Purpose It was the case. Ipang just elaborated on what I said cause I pointed out the return statement.

Answer 5

I believe it's because your check function is taking every key element passed into it and making the value ocean based on the return statement. I may be wrong though.

Answer 6

@justice I don't think that's the case,that's the pattern I use on some other occasions and it has always worked

Answer 7

I didn't really understand the way you put it across @Justice.Thanks all the same.

Answer 8

steve Purpose

When I said "Your check function..." the check function is checkCreatures().

"...is taking every key element passed into it... " The Key would be "lion".

"... and making the value ocean... " The value was "jungle" and turned it into "ocean".

"...based on the return statement." This is where Ipang expands on what I said and tells you that you should that instead of using the assignment operator, you should use the equality.
