Signature

array.pop   #=> object or nil

array.pop removes and returns the last object from array. nil is returned if array is empty (which is not a good test for an empty array since the last object of the array could itself be nil).

Examples

stack = []
stack.pop           #=> nil
stack.push(1,2,3)   #=> [1, 2, 3]
stack.pop           #=> 3
stack               #=> [1, 2]
stack.push(nil)     #=> [1, 2, nil]
stack.pop           #=> nil
