Saving both time and frustration
The first and most important reasons to consider AngularJS training is the possibility to actually recover your lost time. Developing applications with AngularJS is very quick, while the effort is out of discussion. Just think about the ng-class and ng-model directives. These are some of the directives that require a lot of time while using jQuery. Saving is also time consuming with jQuery, which asks for a new object every time you do it. Besides, you need some event handlers and a little attention to small details. All these things become history once you learn how to implement AngularJS into your web applications.
Considering the overall maintenance
Handling application architecture in a more efficient manner
There are plenty of problems in the architecture of particular applications. Complex applications are obviously exposed to a series of script issues. For example, some objects in the server code are not always underlined as objects in the client code. They do not look and feel like codes because they have different methods, not to mention about those situations when they are hidden or overwhelmed by data attributes. Handling such complex scripts is clearly a challenging task. But fortunately, AngularJS brings in ng-resource. You are now allowed to develop services that can successfully match the REST APIs. Another major benefit is the possibility to handle objects on the client side in the exact same way you operate objects on the server side.
With these considerations in mind, it is no surprise why more and more people take AngularJS training. The respective technology is very likely to revolutionize web applications in the future.
