How would you optimize watch expressions in AngularJS for better performance?

Thank you for posing such a critical question, especially in the context of AngularJS applications, where optimizing watch expressions can significantly enhance performance. Drawing from my extensive experience in developing high-performance web applications, particularly in roles that have required deep expertise in AngularJS, I've developed a nuanced approach to optimizing watch expressions that I believe will be invaluable for this Frontend Developer position. Firstly, it's essential to clarify our understanding of watch expressions in AngularJS. Watch expressions are used to monitor changes in variables or expressions; however, they can quickly become a performance bottleneck if not managed carefully. My strategy focuses on minimizing the number of active watch expressions, reducing the complexity of those expressions, and making judicious use of AngularJS's built-in features to mitigate performance issues. One effective strategy is to limit the scope of watch expressions...
