How do I use blocks in Ruby?

In Ruby, blocks are chunks of code that can accept input and be passed to methods. They are defined using either braces {} or the do...end syntax.

Can you give me an example of a block in Ruby?

Sure! Here's a simple example:

[1, 2, 3].each do |number|
  puts number * 2
end

This will print each number in the array multiplied by 2.

What are the benefits of using blocks?

Blocks allow for cleaner and more readable code, enabling you to pass behavior to methods without needing to create separate methods for each action.

Are there any common pitfalls when using blocks?

Yes, one common pitfall is forgetting that blocks are not objects. They cannot be stored in variables or passed around like methods.
