How to define an Array with X nil values?

Question

I have an integer with a value

I want to create an array with nil values representing this integer

For example:

i = 5
# The result i want is
[nil, nil, nil, nil, nil]

What is the most Ruby way of doing this? Aka, the shortest way. Without need of looping et c.

It took you more time to write this question than it would have taken to check the Array documentation. — Mark Thomas

This is very basic question:

i = 5
Array.new(i) #=> [nil, nil, nil, nil, nil]

i = 5
[nil]*i #=> [nil, nil, nil, nil, nil]
