Method: Enumerable#sort

Defined in:

enum.c

#sort ⇒ Array #sort {|a, b| ... } ⇒ Array

Returns an array containing the items in enum sorted, either according to their own <=> method, or by using the results of the supplied block. The block should return -1, 0, or +1 depending on the comparison between a and b. As of Ruby 1.8, the method Enumerable#sort_by implements a built-in Schwartzian Transform, useful when key computation or comparison is expensive.

%w(rhea kea flea).sort          #=> ["flea", "kea", "rhea"]
(1..10).sort { |a, b| b <=> a }  #=> [10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

Overloads:

• #sort ⇒ Array

  Returns:

  • (Array)
• #sort {|a, b| ... } ⇒ Array

  Yields:

  • (a, b)

  Returns:

  • (Array)
