What are some common use cases for lambdas and procs in programming?

Lambdas and procs are often used for callbacks, event handling, and functional programming techniques. They allow for concise code.

Can you give me an example of using a lambda in Ruby?

Sure! In Ruby, you can use a lambda to create a simple function. For example: my_lambda = ->(x) { x * 2 }.

How do procs differ from lambdas?

Procs are more flexible with arguments and can return from the enclosing method, while lambdas enforce argument checks.

When should I use a lambda instead of a proc?

Use a lambda when you need strict argument checking and want to maintain the return behavior of the calling method.
