Description: NgZone is a fundamental service in Angular that allows developers to execute code inside or outside of Angular’s zone, which can help with performance optimizations. Angular uses a change detection system to update the view when data changes, and NgZone plays a crucial role in this process. By encapsulating code in a specific zone, Angular can know when it should perform change detection and when it can skip it, improving the application’s efficiency. NgZone provides methods like ‘run’ and ‘runOutsideAngular’, allowing developers to control the execution context of their code. This is especially useful in situations where operations do not require view updates, such as with third-party events or asynchronous tasks. By using NgZone, developers can optimize the performance of their Angular applications, ensuring that change detection only runs when necessary, resulting in a smoother and faster user experience.
