Yields x to the block, and then returns x. The primary purpose of this method is to “tap into” a method chain, in order to perform operations on intermediate results within the chain.

(1..10).tap { |x| puts "original: #{x.inspect}" }.to_a.
  tap    { |x| puts "array: #{x.inspect}" }.
  select { |x| x%2 == 0 }.
  tap    { |x| puts "evens: #{x.inspect}" }.
  map    { |x| x*x }.
  tap    { |x| puts "squares: #{x.inspect}" }

Yields:

  • (_self)

Yield Parameters:
