What are the differences between lambdas and procs in Ruby?

In Ruby, both lambdas and procs are used to create blocks of code that can be executed later, but they have some key differences.

Can you give me an example of a lambda?

Sure! Here's a simple lambda example:

my_lambda = ->(x) { x * 2 }
puts my_lambda.call(5)  # Output: 10

What about a proc?

Here's an example of a proc:

my_proc = Proc.new { |x| x * 2 }
puts my_proc.call(5)  # Output: 10

What are the differences in how they handle return statements?

Lambdas check the number of arguments and return control to the calling method, while procs do not check arguments and return from the enclosing method.
