What is the difference between Proc and Lambda in Ruby?

What is the difference between Proc and Lambda in Ruby?

In Ruby, both Proc and Lambda are objects that encapsulate blocks of code, but they have some key differences.

Can you explain those key differences?

Sure! One major difference is how they handle the return keyword. In a Proc, return will exit the enclosing method, while in a Lambda, it will only exit the lambda itself.

Are there any differences in argument handling?

Yes! Lambdas enforce the number of arguments, while Procs do not. If you pass the wrong number of arguments to a lambda, it will raise an error.

Which one should I use in my Ruby code?

It depends on your needs. Use a lambda when you want strict argument checking and a Proc for more flexibility.
