 You can create multiple **immutable references** to a value, but you cannot have a mutable reference while immutable references exist. This allows you to read from the value without changing it.

+## Using `&` to Create References
+
+In the example above, `&s1` creates an immutable reference to `s1`. This means that `calculate_length` borrows `s1` but does not take ownership of it. The `&` symbol is used to denote a reference in Rust. This allows the function to access the value without taking ownership, which means `s1` can still be used after the function call.
+
+Similarly, in the function signature `fn calculate_length(s: &String) -> usize`, `&String` indicates that the parameter `s` is an immutable reference to a `String`. This allows the function to read from the `String` without modifying it or taking ownership.

 ## Challenge
 
 In this challenge, you will create a function `calculate_length` that takes an immutable reference to a `String`, calculates its length, and returns the length.
