times()public
Iterates the given block int times, passing in values from zero to int - 1.
If no block is given, an Enumerator is returned instead.
5.times {|i| print i, " " } #=> 0 1 2 3 4
1Note
collect/map
If you'd like to use this method for something like Enumerable#collect, you are looking at the wrong place. This method will return the initial integer, not the values from the block.
a = 20.times { |n| n * 2 } #=> 20
Instead, use Range#collect:
a = (0...20).collect { n * 2 }
