If say I have an array and I would to iterate through the array, but do something different to the first and last element. How should I do that?

Taking the below code as example, how do I alert element a and e?

for element in array
  console.log(element)

    You can retrieve the first and last elements by using array destructuring with a splat:

    [first, ..., last] = array
    

    This splat usage is supported in CoffeeScript >= 1.7.0.
