In the recent times, we have seen that development in Angular JS has increased considerably. There is a need to enhance development with Angular JS and these needs to be taken care with the following processes.
Here are few things that can help you in creating amazing web apps in Angular JS. This will then tell what needs to be done for the watchers so that you can make sure that Angular JS development can be good for web app development
Angular Watchers
If you are using too many watcher than you need to be careful while using them as it can make your app slow. There is much tracking happening when changes are being made to the app. Thus, you need to see if any updation required. Run the digest cycle again. The watcher is depended upon additional watcher then it will continue until you update the app. You can reduce or avoid using no repeat as it created poor performance.
Watch Collection is Good
If you are using 3rd parameter, then I would recommend using watch collection. This is faster and improves performance in Angular JS. The watch collection is more like watch and it checks with first layer. This way the performance can be improved.
Use Batarang
It is very effective tool for development in Angular JS open source framework. It comes handy in debugging the Angular JS apps. It offers robust development of Angular web apps. It offers Angular suited rich features.
Use console.time
It is very effective and powerful API which is very useful for debugging processes. It is being preferred by many app development experts. You can use console. time to call profile only with a few variables. This sub-millisecond resolution will also be provided.
Angular JS and its watchers can slow your web app, so using these tools can improve the performance of Angular JS. For more information, post your queries or post a question in the Angular Community of developers.
