What are Ruby blocks and how do they work?

Can you explain what Ruby blocks are?

Sure! Ruby blocks are anonymous pieces of code that can accept input and be passed to methods. They are enclosed in either braces {} or do...end.

How do I use a block with a method?

You can pass a block to a method by using the yield keyword inside the method. For example, def my_method followed by yield will execute the block when the method is called.

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

Absolutely! Here's a simple example: def greet followed by yield and then calling greet { puts 'Hello!' } will output 'Hello!'.

What are the benefits of using blocks in Ruby?

Blocks allow for cleaner code, better abstraction, and can help with iteration and callbacks, making your code more flexible.
