What are some common errors when using mutable arrays?

Common errors with mutable arrays include index out of bounds, unintended mutations, and memory leaks.

Can you explain what index out of bounds means?

Index out of bounds occurs when you try to access an array element using an index that is not valid, like negative indices or indices greater than the array length.

How can I avoid unintended mutations?

To avoid unintended mutations, consider using immutable data structures or always creating a copy of the array before modifying it.

What are memory leaks in the context of arrays?

Memory leaks happen when you lose reference to an array without freeing its memory, leading to wasted resources.
