Code blocks


Code-blocks in Ruby are pieces of multiline code written in curly brackets or within a do..end block that can be passed around to methods such as parameters.

While discussing arrays, we saw the following:

arr.each do |e|
  puts e
end

Here, lets see what the preceding code will do:

do |e|
  puts e
end

This is a code-block which is passed as a parameter to the arr.each function.

Apart from passing code, code-blocks can be used to implement iterators and callbacks.
