For even more undifferent emptiness, read up on positive and negative zero.
But please don't make a kata out of it. :P
...aaaand here ya go
and so on...
Two more reasons not to do it .. :D
You are expecting unstandard behaviour for JS. Even if you're going to specify it, it's not a good idea.
NaNshould not be equal toNaN, and holes in sparse arrays do not have "variables" ( ie, values ) to change.hmm ok, I won't publish this kata then.
Well, you can, but I would stay closer to standard JS behaviour. Do not fill holes in sparse arrays ( or explicitly specify that behaviour - it does make for interesting programming ), do not require
NaN === NaN( really, just don't go there ), but otherwise replace existing values withnullwhere applicable, and you won't hear me.In light of below issue, it might be a good idea to specify all that, if only with the text "according to standard JS behaviour", though.
And with random tests. ( Did you read the documentation on creating your first kata? It still applies to your second one. :)
Resolved by retirement. Closing.
Hi,
I fear the description is way less than sufficient... :o
And you need random tests.
cheers
