AngularJS should be with your top attention when choosing the right JS framework. However, in order to make the options process fair, it is necessary to take into a discussion of its pros and cons.
- The aggressive client-side programming language is clubbed with HTML and CSS to extend and advance web performance.
- AngularJS is one of these frameworks and popular among the developers of rich cyberspace applications.
- AngularJS was born in 2009 as a component of a more immensely colossal commercial product, called GetAngular.
- Large organizations like PayPal, Freelancer, LinkedIn, Lego, Hopscotch and several others are powering their UIs by AngularJS.
- Angular makes it easier to work with dynamic rendering with its JSON based processing and rendering capabilities.
- Angular has been developed with the vision of making it modular, testable and maintainable.
- The latest version of Angular JS is 1.7.4 released in September 2018.

Getting Started: Angular JS
- Dependency Injection – js has built-in dependency injection (DI) that helps natural development, understanding, and testing.
- Data-binding – The two-way data-binding feature saves developers from writing a lot of code. It is the automatic synchronization of data between model and view components.
- It can be configured in MVC as well as MVW architecture.
- Services − are a set of code that can be shared by different components of an application.
- Directives – With this feature, it becomes easy to create custom HTML tags that act like new custom widgets. It can also be used to manipulate DOM attributes.
Pros of AngularJS
- Two-way data binding -AngularJS facilitates faster and easier data binding which doesn’t require a developer to intervene at all.
- DOM manipulation -the developer saves time and efforts to code, translate and update the DOM elements.
- Improved server performance -it only serves static files and responds to the API calls.
- Responsive web – AngularJS makes it possible by letting responsive, fast-loading and seamlessly -navigating websites and apps.
- Use of directives -AngularJS makes use of directives that keep the scripts and HTML pages mess-free and extremely organized.
Let’s See in Detail.
Faster application prototyping
Fast prototyping is indeed a buzzword thanks to the availability of frameworks like Angular. In no time and by writing somewhat less code, you can develop app prototypes with good functionality, get feedback and make changes outside getting annoyed.
Two-way data binding
AngularJS facilitates faster and easier data required which doesn’t require a developer to involve at all. Referred to as two-way data binding, it ensures that changes made to view are directly displayed in the model and vice-versa.
There’s nothing better than organized an outstanding end-user training and AngularJS makes it possible by letting responsive, fast-loading and seamlessly-maneuver websites and apps.
Improved server performance
Because it helps caching and many other techniques, Angular reduces the burden from server CPUs. It means that the server functions extremely well thanks to decreased traffic and because it only serves immobile files and responds to the API calls.
Highly testable products
One of the elemental aspects of Angular is that it frames highly testable websites and applications. By own unit testing and end-to-end testing, it takes trial and debugging much simpler than you can imagine. Dependency needle, for example, allows various peripheral to be isolated and mocked. Protractor, Jasmine, and Karma are other exclusive testing tools that the framework offers.
Use of directives
AngularJS makes use of mandate that keeps the scripts and HTML pages mess-free and awfully organized. These allow creating separate codes by cramming together specific functions and using them regularly. Apart from a set of a pre-defined edict, the framework also allows a builder to create custom directives.
The Plain HTML templates
That AngularJS uses plain HTMP templates is another awesome aspect. Going further, the templates are far to the compiler as DOM elements and not as rope and this particular advantage ensures better plan. Moreover, it allows for easy control, extension, and reliability of templates.
Cons of AngularJS
Other difficult features
Instruction is difficult to use too. In addition, many AngularJS features like dependency injections and firm can be problematic for the more classical developers. Either you use a lot of time considering them or hire an experienced AngularJS development team.
Largely layered and arranged hierarchically, scopes can be complicated entities to handle if it is your first involvement with Angular. One of the most difficult tasks could be debugging the scopes.
Inexperience with MVC
If you are a developer who follows the usual approach and is unconditionally unfamiliar with the Model-View-Controller architectural patterns, using Angular can be extremely time-taking. In case you have hard deadlines to meet, this might not be the right way to go. A resolution, however, could be to hire some experienced if you wish to unlock the framework’s advantages.
Rather than ensuring a straight learning graph, you can have to face great trouble in getting adapted to the framework. However, the Definite documentation available may further disturb the learning process. However, the day-by-day approaching community is making it simpler.
Capable AngularJS developers deal with these as minor hiccups as they openly promote its exciting cons. The framework is finitely worth bothersome once.
