Answer from AI
Linked lists are a data structure where each element contains a reference to the next (and sometimes the previous) element.
Advantages:
- Dynamic resizing without the need for memory reallocation.
- Fast insertion and deletion of elements in the middle of the list (without shifting other elements).
Disadvantages:
- Lack of direct index access, making element search slower (O(n)).
- Additional memory for storing references.
- Poor data locality, which can slow down performance due to cache misses.
In Node.js, linked lists can be useful, for example, for implementing queues or stacks with frequent insertions and deletions, where the performance of insert/delete operations is more important than quick index access.
