Methods in Ruby on rails
By: Brian Marick in Ruby Tutorials on 2008-10-17
Ruby methods let you create new verbs (messages) in the Ruby lan- methods guage. It's a bit confusing that two closely related ideas-messages and methods-have such similar names.
Delimiting Blocks
Blocks can start with a do and end with end, or they can start with { and end with }. The following two snippets of code mean the same thing:
array.each do | element |
puts element
end
array.each { | element |
puts element
}
My sense is that Rubyists prefer the first except for short blocks, especially those that can fit on one line:
array.each { | element | puts element }
