Reference

1. Use references when you want to share access to a value without transferring ownership. This can help reduce memory usage and avoid unnecessary cloning of values.
2. Use mutable references (&mut) when you need to modify the borrowed value. Remember that you can have multiple immutable references or only one mutable reference at a time.
3. When iterating over a collection, you can use references to avoid moving or copying the elements. For example:

   for (key, value) in &my_hashmap {
       // ...
   }

4. When using methods that borrow values, such as get() for a HashMap, the returned value will be a reference. You should use the appropriate reference type when working with these values.
5. When passing values to a function, prefer using references if the function doesn't need to own the value or if you want to avoid cloning or copying the value.
