What are lambdas in Ruby?
An example of an AI chatbot conversation about lambdas in Ruby programming.
What are lambdas in Ruby?
Lambdas in Ruby are anonymous functions that can be stored in variables and passed as arguments.
How do I define a lambda in Ruby?
You can define a lambda using the -> syntax or the lambda method. For example: my_lambda = -> { puts 'Hello!' }.
What is the difference between a lambda and a proc?
The main difference is that lambdas check the number of arguments, while procs do not. Lambdas also return from the lambda itself.
Can you give me an example of using a lambda?
Sure! Here's an example: my_lambda = ->(x) { x * 2 }; puts my_lambda.call(5) will output 10.
