An example of an AI chatbot conversation about the differences between map and select in Ruby.
What is the difference between map and select in Ruby?
In Ruby, map transforms each element of a collection, while select filters elements based on a condition.
Can you give me an example of how to use both?
Sure! For map, you might do array.map { |x| x * 2 } to double each element. For select, array.select { |x| x.even? } would return only even numbers.
Are there any performance differences between them?
Yes, map processes every element, while select only processes elements that meet the condition, which can affect performance based on the size of the collection.
