CoffeeScript, what can I tell ya - I didn’t want to love it.
I have an unreasonable grudge against significant whitespace.
I couldn’t figure out the value of a language that compiles to another reasonable language.
And don’t even get me started on the for of/in thing. I still don’t understand that.
But the more I use CoffeeScript, the more I love it.
The lambdas are probably my biggest love - how can you not love them, in comparison to what JavaScript makes you do?
However, I found something out the other day that seems slightly counter-intuitive to me.
supposedToBeArray = null
if foo in supposedToBeArray
# You will never reach this code, because the line above throws an exception.
I guess my thought would be if foo in supposedToBeArray would return false. But nope, throws when the object is not an array (or is not array-like).
