What are some common mistakes when using associative arrays?

Some common mistakes include using non-string keys, forgetting to initialize arrays, and confusing associative arrays with regular arrays.

Can you explain why using non-string keys is a mistake?

Using non-string keys can lead to unexpected behavior, as many languages will convert them to strings, which may not be what you intended.

What happens if I forget to initialize an associative array?

If you forget to initialize it, you may encounter errors when trying to access or assign values, as the array won't exist yet.

How can I avoid these mistakes?
