What is binding?

In SwiftUI, a binding is a mechanism that creates a two-way reference to the state of another view. It allows a view to read and write to a piece of state that is managed elsewhere, enabling the view to reflect changes in the state and update the state based on user interactions. For example, if you have a view that allows users to rate something, you can use a binding to connect the view's controls (like buttons) to the state that holds the current rating. This way, when the user interacts with the controls, the state is updated, and the view automatically reflects these changes.
