What are blocks and procs in Ruby?

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’s the difference between a block and a proc?

The main difference is that a block is not an object and cannot be stored in a variable, while a proc is an object and can be assigned to a variable.

Can you give me an example of using a proc?

Certainly! You can define a proc like this: my_proc = Proc.new { |x| x * 2 }, and then call it with my_proc.call(5) which returns 10.
