What are iterables in programming languages?

What are iterables in programming languages?

Iterables are objects that can be iterated over, meaning you can traverse through their elements one at a time. Examples include lists, tuples, and sets.

Can you give examples of iterables in Python?

Sure! In Python, lists, tuples, dictionaries, and sets are all iterables. You can use a for loop to iterate through them.

How do iterables differ in JavaScript?

In JavaScript, iterables include arrays, strings, and objects with a Symbol.iterator method. You can use the for...of loop to iterate over them.

What about in Java?

In Java, iterables are represented by the Iterable interface, which allows you to use an iterator to traverse collections like ArrayList and HashSet.

Are there any performance differences between iterables in different languages?

Yes, performance can vary based on the language's implementation of iterables and the underlying data structures used. Generally, languages optimize their iterables differently.
