What are some common mistakes when using procs and lambdas in Ruby?

Some common mistakes include misunderstanding scope, not using parentheses correctly, and confusing procs with lambdas.

Can you explain the difference between procs and lambdas?

Sure! Procs are more flexible with arguments and return values, while lambdas enforce strict argument checking.

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

If you pass the wrong number of arguments to a lambda, it will raise an ArgumentError. Procs, on the other hand, will not.

Are there any performance differences between using procs and lambdas?

Generally, the performance difference is negligible, but lambdas can be slightly slower due to stricter argument checking.
