How do I use enumerable methods in Ruby?

Enumerable methods in Ruby allow you to traverse, search, and manipulate collections like arrays and hashes. Would you like examples?

Yes, can you show me some common methods?

Sure! Common enumerable methods include map, select, and reduce. For instance, map transforms each element in an array.

Can you give me a code example of using map?

Absolutely! Here's a simple example: array = [1, 2, 3]; array.map { |n| n * 2 } will return [2, 4, 6].

What about select? How does it work?

The select method filters elements based on a condition. For example, array.select { |n| n.even? } returns only the even numbers.
