How to initialize an array in one step using Ruby?

Question

I initialize an array this way:

array = Array.new
array << \'1\' << \'2\' << \'3\'

Is it possible to do that in one s

Answer 1

To prove There's More Than One Six Ways To Do It:

plus_1 = 1.method(:+)
Array.new(3, &plus_1) # => [1, 2, 3]

If 1.method(:+) wasn't possible, you could also do

plus_1 = Proc.new {|n| n + 1}
Array.new(3, &plus_1) # => [1, 2, 3]

Sure, it's overkill in this scenario, but if plus_1 was a really long expression, you might want to put it on a separate line from the array creation.
