What are the best practices for using arrays and objects in programming?

When using arrays, it's important to keep them organized and avoid deep nesting. For objects, use meaningful keys and keep them flat.

Can you explain why deep nesting is a bad practice?

Deep nesting can make your code harder to read and maintain. It can also lead to performance issues and bugs.

What are some common mistakes to avoid with arrays?

Common mistakes include using arrays for non-sequential data, not validating input, and forgetting to handle edge cases.

How can I improve the performance of my array operations?

You can improve performance by using methods like map, filter, and reduce instead of for loops, and by minimizing the size of your arrays.
