What are the differences between procs, lambdas, and methods in Ruby?

Can you explain the differences between procs, lambdas, and methods in Ruby?

Sure! In Ruby, procs and lambdas are both types of closures, but they have some key differences. Procs are more flexible with arguments, while lambdas enforce strict argument checking. Methods, on the other hand, are defined with the def keyword and are more structured.

What happens if I pass the wrong number of arguments to a proc?

If you pass the wrong number of arguments to a proc, it won't raise an error. Instead, it will assign nil to any missing arguments and ignore extra ones.

And what about lambdas?

Lambdas are stricter. If you pass the wrong number of arguments to a lambda, it will raise an ArgumentError.

Can you give me an example of when to use each?

Certainly! Use methods for general functionality, procs for callbacks or blocks of code, and lambdas when you need strict argument checking.
