What are the performance differences between blocks and procs in Ruby?

In Ruby, blocks are generally faster than procs because they are more lightweight. Blocks are not objects, while procs are.

Can you explain why blocks are faster?

Blocks are optimized by the Ruby interpreter, allowing for quicker execution. Procs, being objects, have additional overhead.

Are there any scenarios where I should prefer using procs?

Yes, use procs when you need to pass around a callable object or when you want to store a block for later execution.

What about lambdas? How do they compare?

Lambdas are similar to procs but have stricter argument checking and return behavior, making them more predictable in certain contexts.
