What are the differences between Enumerable methods and Iterators in Ruby?

What are the differences between Enumerable methods and Iterators in Ruby?

Enumerable methods are higher-level methods that operate on collections, while Iterators are lower-level constructs that allow you to traverse through elements.

Can you give me examples of both?

Sure! An example of an Enumerable method is map, which transforms elements, while an Iterator example is each, which simply iterates over elements.

When should I use Enumerable methods instead of Iterators?

Use Enumerable methods when you need to perform operations on collections, like filtering or transforming data. Use Iterators for simple traversal.

Are there performance differences between them?

Yes, Enumerable methods can be less performant due to their higher-level abstractions, while Iterators are generally faster for simple tasks.
