What are some common array methods in Ruby?
In Ruby, common array methods include map, select, reject, each, and reduce. Would you like examples of any specific method?
Yes, can you explain how the map method works?
Sure! The map method creates a new array by applying a block of code to each element of the original array. For example, [1, 2, 3].map { |n| n * 2 } returns [2, 4, 6].
What about the select method?
The select method returns a new array containing all elements for which the given block returns true. For instance, [1, 2, 3, 4].select { |n| n.even? } returns [2, 4].
