Question

I have a function where if successful, it returns an integer, but if not it just returns false.

Here’s part of my code:

    function hellofunc(x) {
//....

        if (returnvalue.length == 1) {
            return returnvalue[0];
        } else if (returnvalue.length > 1) {
            return returnvalue[rx(0, returnvalue.length - 1)];
        } else {
            return false;
        }
    }

When the function calls this -> return returnvalue[0]; it gives 0 as an integer.

But when I call hellofunc(something); I see it writes to console “0” but when I type something false it returns false,

JavaScript thinks 0 is false? So what do I do here? Do I do this?

hellofunc(something)!==false

Or is there any better solution?

Answer 1

hellofunc(something) !== false

as you said..no better solution..:)
