What are blocks and procs in Ruby?
An example of an AI chatbot conversation about blocks and procs in Ruby programming.
Can you explain what blocks and procs are in Ruby?
Sure! In Ruby, a block is a chunk of code that you can pass to methods, while a proc is an object that encapsulates a block.
How do I create a block in Ruby?
You can create a block by using either curly braces or the 'do...end' syntax. For example: array.each { |item| puts item }.
What about procs? How do they differ from blocks?
Procs are objects that can be stored in variables and passed around. Unlike blocks, they can be called multiple times.
Can you give me an example of using a proc?
Certainly! Here's an example: my_proc = Proc.new { |x| x * 2 }; my_proc.call(5) will return 10.
