How does scope $digest cycle work in AngularJS for updating the view?

It iterates through all the watches and updates the model accordingly
It only updates the watches registered with $digest
It updates the model and view simultaneously
It updates the view directly without involving watches

The scope $digest cycle in AngularJS works by iterating through all the watches registered with the scope. During each iteration, it checks for changes in the model and updates the corresponding watches. This process continues until no more changes are detected. Understanding the $digest cycle is crucial for developers to optimize performance and avoid potential issues related to data binding and updating the view.
