How do you debug an AngularJS application?

Thank you for presenting such an insightful question. Debugging is indeed a critical aspect of any development process, especially in the dynamic environment of AngularJS applications. My approach to debugging AngularJS applications is methodical and leverages both built-in AngularJS features and external tools to ensure comprehensive coverage and efficient resolution of issues. First and foremost, I often start with the AngularJS built-in tool $scope.$watch, which allows me to observe changes in the scope's variables. This is particularly useful for identifying issues related to data binding, one of the common challenges in AngularJS applications. By monitoring how and when data changes within the scope, I can pinpoint inconsistencies or unexpected behaviors that might be at the root of the problem. In addition to AngularJS’s own capabilities, I extensively use the Chrome Developer Tools, especially for performance profiling and tracking down JavaScript errors...
