What is the difference between blocks and methods in Ruby?

What is the difference between blocks and methods in Ruby?

In Ruby, methods are defined with the def keyword and can be called with arguments, while blocks are anonymous pieces of code that can be passed to methods.

Can you give me an example of a block?

Sure! Here's a simple example: array.each { |element| puts element } uses a block to iterate over each element in the array.

How do I define a method that takes a block?

You can define a method that takes a block by using the &block syntax. For example: def my_method(&block) block.call end.

Are blocks and methods interchangeable?

Not exactly. While they can sometimes achieve similar outcomes, blocks are more flexible for passing chunks of code, whereas methods are better for reusable code.
