What are some examples of using map and select in Ruby?

Can you explain how to use map and select in Ruby with examples?

Sure! The map method transforms each element in an array, while select filters elements based on a condition.

Can you give me a simple example of using map?

Absolutely! For instance, if you have an array of numbers and want to double each number, you can do: numbers.map { |n| n * 2 }.

What about using select? Can you show me that?

Of course! If you want to select even numbers from an array, you can use: numbers.select { |n| n.even? }.

Are there any differences in performance between map and select?

Yes, map creates a new array with transformed elements, while select creates a new array with filtered elements. Their performance can vary based on the size of the array and the complexity of the block.
