Duplicate!

Pretty sure the test cases are broken. Once you get to random testing, the tests expects you to return false on invalid input instead of throwing an error.
Also the description should probably be more detailed about dropping the center character on input with odd length.

whoa.

Thank you JavaScript for even letting me do that.

Codewars chat room! That is all.

While I really like the idea, this kata needs some work.

• The test cases are not thorough enough – I entered a completely broken solution and it worked, which should never happen :P
• The whole prototype shenanigans is unnecessary since you don't need to preserve any state on subsequent calls of readCommands. So either build a more complex apparatus out of this or get rid of it entirely and make it a function!
• The problem could be a bit more contrived and complicated. q1 is basically useless which leaves you with 2 states, which is hardly worth building a FSM for. (How's writing the control for an elevator sound? Maybe I'll make a kata out of that)
• Too easy for 4-kyu.

Exactly the same as this kata

Minor thing - found a typo:
var knightEngine = compose(moveKnightRandom, moveKnightRandom, moveKnightRandom); //It will perform tree random movements
Should probably be 'three'!

Apart from that, really cool kata! I'm all about shoe-horning functional paradigms into my favourite languages.

How is this a best practice?

I know this example is somewhat overused, but I still want to point out how awesome it is that in Haskell you can write quicksort in a mere two lines of code.

Looks like someone coded too much LISP lately :P

Bump! It has been four months now.
