# Ruby Yield Statement


# Yield statement is used for a method that takes in a block and needs to invoke the code block.
# In this e.g, name() method takes in a block defined in line #10. 
# In the method definition, wherever 'yield' keyword comes up, the code block is rendered.

def name
  puts "A yield will be called with id of 12"
  yield 12
  puts "A yield will be called with id of 14"
  yield 14
end

name {|i| puts "I am called by yield name #{i}"}

#// Output:
#// A yield will be called with id of 12
#// I am called by yield name 12
#// A yield will be called with id of 14
#// I am called by yield name 14
