I'm hanging my head in such utter shame right now. Thanks for the help.

from the African countries that start with the character E

You're searching for "African countries that end with the character E" instead.

Remember that the number scale is 0-10, while the moon scale is 0-5. This means a value of 1.5 equals 0.75 moons. Which should round up to 1 and produce a single "o", which gives a final string of "oxxxx".

This was a lot of fun

Ah, ok, thanks.

Your code only counts types of braces and it's not accounting for the right position.

Javascript - Last 5 tests fail, but the rest, including the random tests, pass?

Probably you're using match that can return null if there is no match. But it's just a guess without seeing your code.

That's what I would like to know! I can share my code - which is just an if statement counting the occurences of each character. Like I said, my code works everywhere but here.

you're trying to get a length from a null object, however 0 <= input.length <= 100 so where is this null object coming from?

In javascript I keep getting "TypeError: Cannot read property 'length' of null" for a single test. I do use the string length property. I have tried handling a null string every way I can find. My code works in codepen and repl so I don't know why it generates this error here. Any suggestions?
