# My answer at the time was to do something like this
[[nil]*3]*4
#=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]

# The next question was whether I knew some initializer to do that for us.
# Apparently, there is:
Array.new(4) { Array.new(3) }
#=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]

# But that wasn't the brainwave my brain came up with just now.

Randomize array element order in-place.
Using Fisher-Yates shuffle algorithm.

Array.prototype.shuffle = ->
  for i in [(@length - 1) .. 0]
    j = Math.floor(Math.random() * (i + 1))
    [@[i], @[j]] = [@[j], @[i]]
