How does Angular finalize an execution cycle?

By refreshing the browser view completely
By applying all updates and refreshing the DOM
By compiling the application again
By stopping any running processes

The correct answer is: By applying all updates and refreshing the DOM

In Angular, finalizing an execution cycle primarily involves applying all changes and refreshing the Document Object Model (DOM) to reflect the latest state of the application. This process is part of Angular's change detection mechanism, which efficiently updates the user interface whenever there are data changes. Angular's change detection works by comparing the current state of the model with the previous state. When a change is detected—such as a user interaction or a data update—the framework performs the necessary updates to the DOM elements. This ensures that the displayed information is accurate and corresponds to the current application state. By focusing on updating only what's necessary rather than reloading or refreshing the entire browser view, Angular optimizes performance and enhances the user experience. Thus, the finalization of an execution cycle is about efficiently applying updates to the DOM based on the latest computed data, ensuring a seamless interaction for users.
