What are the differences between arrays and sets in Ruby?

What are the differences between arrays and sets in Ruby?

Arrays and sets in Ruby are both collections, but they have key differences. Arrays are ordered and can contain duplicates, while sets are unordered and do not allow duplicates.

Can you give me an example of when to use a set instead of an array?

Sure! Use a set when you need to ensure all elements are unique, like storing user IDs. An array is better for maintaining order.

How do I create a set in Ruby?

You can create a set in Ruby by requiring the 'set' library and then using Set.new to initialize it. For example: require 'set'; my_set = Set.new([1, 2, 3]).

What methods are available for sets in Ruby?

Sets in Ruby have methods like add, delete, include?, and union. You can explore more in the Ruby documentation.
