What are iterators in programming languages?
Iterators are objects that allow you to traverse through a collection, like lists or arrays, without exposing the underlying structure.
Can you give me examples of languages that support iterators?
Sure! Languages like Python, Java, and JavaScript all support iterators, allowing for easy iteration over collections.
How do iterators differ from regular loops?
Iterators provide a more abstract way to traverse collections, often with built-in methods, while loops require manual indexing.
Are there any performance benefits to using iterators?
Yes, iterators can improve performance by reducing memory usage and providing lazy evaluation, which processes items only as needed.
