An example of an AI chatbot conversation about advanced lambdas in Ruby programming.
What are advanced lambdas in Ruby?
Advanced lambdas in Ruby are anonymous functions that can capture variables from their surrounding context and can be used for more complex operations.
Can you give me an example of using lambdas with parameters?
Sure! Here's an example: my_lambda = ->(x) { x * 2 } and you can call it with my_lambda.call(5) which returns 10.
How do lambdas differ from procs in Ruby?
Lambdas check the number of arguments passed, while procs do not. If you pass the wrong number of arguments to a lambda, it will raise an error.
Can lambdas be used as callbacks?
Yes, lambdas can be used as callbacks in methods, allowing you to pass behavior as an argument.
