In this tutorial, I explored the ngOnChanges lifecycle hook in Angular 18, demonstrating its mechanism, usefulness, and implementation. I started with an introduction to ngOnChanges, highlighting its role in responding to input property changes within Angular components, making it essential for creating dynamic and responsive applications. Next, I provided a step-by-step guide on creating a new component and implementing ngOnChanges to observe changes in input properties through the SimpleChanges object. This included practical examples, such as logging previous and current values of a property to showcase how ngOnChanges can be used for tasks like data validation, executing conditional logic, and triggering external processes based on input changes. Finally, I wrapped up by encouraging viewers to experiment with ngOnChanges in their projects and engage with the content by sharing experiences or questions in the comments.
