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

Oneliner:

array = [] << 1 << 2 << 3   #this is for fixnums.

or

 a = %w| 1 2 3 4 5 |

or

 a = [*'1'..'3']

or

 a = Array.new(3, '1')

or

 a = Array[*'1'..'3']
