There are many reasons why we need them, but let’s just list (collection pun) a few:
- Managing large amounts of data: As applications grow in complexity, they often need to deal with large amounts of data. Collections help store and manage these datasets. They also come with helpful methods that make it easier to perform typical operations on data, such as searching and filtering.
- Storing and manipulating various data structures: Different data structures have...
