Describe a scenario where using a map in Go would be more efficient than using a slice.

When you need to perform key-based lookups efficiently.
When you need to maintain elements in a specific order.
When you need to perform complex data transformations.
When you need to store a collection of heterogeneous data types.

Using a map in Go is more efficient than using a slice when you need to perform key-based lookups efficiently. Maps allow you to associate values with unique keys, and you can quickly retrieve values based on those keys. This is useful in scenarios like caching, where you want to store and retrieve data based on identifiers, or when implementing a dictionary or dictionary-like functionality.
