What are some common errors when using associative arrays?

What are some common errors when using associative arrays?

Some common errors include using incorrect keys, forgetting to initialize the array, and mixing data types.

Can you give an example of using an incorrect key?

Sure! If you try to access an element with a key that doesn't exist, it will return undefined.

What happens if I mix data types in the keys?

Mixing data types can lead to unexpected behavior, as associative arrays may treat keys differently based on their types.

How can I avoid these errors?

You can avoid these errors by consistently using the same data type for keys and checking for key existence before accessing values.
