Learn Recursion by Building a Decimal to Binary Converter - Step 19

Tell us what’s happening:

I seem to be confused about this. I tried, but I’m not quite sure. I tried to do it, but converting to string is what I’m having trouble with.

Your code so far

return decimalToBinary(10);

I would suggest resetting the lesson

Here was the original starting code

return "1";

the lesson wants you to return the binary representation for 10.
right now you are returning 1.

if you are not sure what the binary representation for 10 is then you can google what is the binary version of 10 and there will be dozens of tables with the answer

you do not need to call the function

you need to return a string

hope that helps

I got it. It was easy, not hard.
