1. Keep a Track on the Count of Watchers Angular creates a watcher for every binding. Evaluation and comparison for previous bindings are done at each digest phase. In the end, the number of watchers comes out to be huge. A few watchers are okay but these watchers start getting troublesome when there are hundreds and thousands of them in the code, eventually slowing down the performance of an application in the browser. The Angular community has a standard global maximum limit of 2,000 watchers, so it’s better to keep track of the count of watchers from the very beginning of development. Some developers can write code which counts watchers and thus help in modifying and optimizing the code later. 2. Inability to Use the Available Tools This is one of the most disappointing circumstances since it becomes necessary to utilize a tool sooner or later. For instance, Firefox and Chrome incorporate uncommon improvement strings that involve investigation, mistake yields, and profiling. With the help of these instruments, a developer can discover the errors quickly and save a lot of time.
