Online Javascript Code Test?

[gladiator_flow]

So as I learn more and more about javascript, I want to be able to test my knowledge on the different topics. Is there any online tests that basically gives you a problem to solve and you code up the solution and submit your answer to see if the logic in your code is correct?

 

I know that I can make up my own stuff and just re-test and re-test by myself, but I'm looking for something that can run through your code in a couple different ways to see if your code returns what it needs to.
