Test, ob das hier auch andere lesen können.

I understand x => x as a function just giving back the parameter.
Why are only the true ones counted?

I like that solution because one could easily change the word 'bingo' with 'zakila' for example.

I like.

This working is actually just luck and just works for an uneven array length.
If you add another 1 to the test case [1, 1, 2] it doesn't work anymore.

I don't get the part where c is a boolean but also remembers carrying the number into the next loop.
Why is that?

Edit: got it.
If you add a variable with true to a number the truth equals to one.
So: var a = 5 and var b = true becomes with a + b a solid 6.
Didn't know that.

Amazing. Don't quite get the math though.
A link to an explanation about what's going on here would be much appreciated.

for js guys: console.log takes time :)
(not sure if that qualifies as a spoiler)

I have no clue how I write the test cases for this kata.

Should I ignore them and just try to submit my code?

I don't understand this concept.
Does it mean something like:
(<put-a-function-here>)(<put-the-arguments-here>)

Could you point me in the right direction?

Thank you very much sir!

Is getting the guess variable to evaluate to the second argument of the function a good start?
