AngularJS should be among your top considerations when choosing the right JS framework. However, in order to make the selection process fair, it is essential to take into consideration its pros and cons.

JavaScript is already a well-established technology known for rendering hot digital properties. The dynamic client-side programming language is clubbed with HTML and CSS to extend and improve web functionality. No wonder that a number of web development frameworks based on JavaScript continue to power an ever-increasing number of websites and web applications. AngularJS is one of these frameworks and a favorite among the developers of rich internet applications.

Maintained by Google and supported by a huge community of developers worldwide, AngularJS should be among your top considerations when choosing the right JS framework. However, in order to make the selection process fair, it is essential to take into consideration its pros and cons. Here’s a comprehensive guide to help you decide whether you want to choose AngularJS or not.

Pros of AngularJS

Two-way data binding

AngularJS facilitates faster and easier data binding which doesn’t require a developer to intervene at all. Referred to as two-way data binding, it ensures that changes made to view are instantly displayed in the model and vice-versa.

DOM manipulation

Unlike other popular JavaScript frameworks, Angular conveniently relieves the developer of actively manipulating DOM (Document Object Model), all thanks to its two-way data binding approach. It means that the developer saves time and efforts to code, translate and update the DOM elements.

Improved server performance

Because it supports caching and many other processes, Angular reduces burden from server CPUs. It means that the server performs extremely well thanks to reduced traffic and because it only serves static files and responds to the API calls.

Faster application prototyping

Rapid prototyping is indeed a buzzword thanks to the existence of frameworks like Angular. In no time and by writing significantly less code, you can develop app prototypes with good functionality, obtain feedback and make changes without getting annoyed.

Responsive web

There’s nothing better than arranging an outstanding end-user experience and AngularJS makes it possible by letting responsive, fast-loading and seamlessly-navigating websites and apps.

Highly testable products

One of the underlying aspects of Angular is that it builds highly testable websites and applications. By allowing unit testing and end-to-end testing, it makes testing and debugging much simpler than you can imagine. Dependency injections, for example, allow various components to be isolated and mocked. Protractor, Jasmine and Karma are other unique testing tools that the framework offers.

The MVVM architecture

AngularJS implements Model-View–Controller and Model-View-Viewmodel architectural patterns which lay strong foundations for application performance. With these divisions, the data is separated from design and visual representation which makes even complex web applications easy to manage.

Use of directives

AngularJS makes use of directives that keep the scripts and HTMP pages mess-free and extremely organized. These allow to create independent codes by cramming together specific functions and using them repeatedly. Apart from a set of pre-defined directives, the framework also allows developers to create custom directives.

The Plain HTML templates

That AngularJS uses plain HTMP templates is another amazing aspect. Going further, the templates are passed to the compiler as DOM elements and not as strings and this particular advantage ensures better workflow. Moreover, it allows for easy manipulation, extension and reusability of templates.

Fast development

If you are a fast learner, you can get familiar with AngularJS in no time. And once you feel fully comfortable working with it, you will see that your development efforts and time spent dealing with it will shrink.

Cons of AngularJS

JavaScript support mandatory

Imagine computers and laptops that access your server but their support for JavaScript is disabled. The associated users won’t be able to access your website or web apps. If there are many such users, you can expect your AngularJS-based web properties to be less useful. However, this is not the case with plain HTML-based web.

Inexperience with MVC

If you are a developer who follows the traditional approach and are completely unfamiliar with the Model-View-Controller architectural patterns, using Angular can be extremely time-consuming. In case you have strict deadlines to meet, this might not be the right way to go. A solution however could be to hire some expert if you wish to unlock the framework’s benefits.

The scopes

Quite layered and arranged hierarchically, scopes can be complex entities to handle if it is your first experience with Angular. One of the most difficult tasks could be debugging the scopes.

Other difficult features

Directives are difficult to use too. In addition, many AngularJS features like dependency injections and factories can be problematic for the more traditional developers. Either you spend a lot of time understanding them or hire an experienced AngularJS development team.

Possible time consumption

The browser may take time to render pages of websites and applications designed using the framework. It may happen because the browsers would be overloaded to perform additional tasks like DOM manipulation. However, this drawback is limited only to the old computers and devices. The modern ones, especially the mobile devices, don’t find it challenging at all.

Difficult learning

Rather than following a straight learning graph, you may have to face great difficulty in getting adapted to the framework. Moreover, the limited documentation available may further affect the learning process. However, the day-by-day extending community is making it easier.

Proficient AngularJS developers consider these as minor hiccups as they openly advocate its exciting cons. The framework is definitely worth trying once.
