In CoffeeScript how do you append a value to an Array?
Solution 1:
Good old push still works.
x = []
x.push 'a'
Solution 2:
Far better is to use list comprehensions.
For instance rather than this:
things = []
for x in list
things.push x.color
do this instead:
things = (x.color for x in list)
Solution 3:
If you are chaining calls then you want the append to return the array rather than it's length. In this case you can use .concat([newElement])
Has to be [newElement] as concat is expecting an array like the one its concatenating to. Not efficient but looks cool in the right setting.
