tracking questions

Angular's change detection mechanism is responsible for tracking changes in the application's data model and updating the view accordingly. Angular uses a change detection strategy to determine when to check for changes and update the DOM. By default, Angular employs the 'CheckAlways' strategy, which checks all components on every event or user interaction. However, developers can use the 'OnPush' strategy to optimize performance by only checking components when their input properties change. Change detection helps ensure that the user interface remains in sync with the application's state, enhancing the responsiveness and accuracy of the application.
