What is AngularJS?
Benefits of Using AngularJS
1. Work fast using $applyAsync
We already know that twoway binding is a unique selling point of AngularJS. And in order to make it a breeze, Angular comes loaded with a magical component called $digest cycle. This cycle gets activated whenever any kind of user interaction happens that Angular is familiar with. Angular latest version 1.3 has a feature that allows you to share a running $digest cycle among a variety of $digest cycle across different XHR calls.
2. Angular handle dependencies
Dependency injection is a feature that has created quite a buzz among Angular fans. And it’s justifiably so because this is something Angular does amazingly. There are two areas where dependency injection bolsters quite well: testing and Single Page Applications.
For testing, Angular makes it possible for you to split your app into logical modules that have dependencies on each other, but can be initialized individually. This is a strategic method to test your app while using only targeted modules. Furthermore, due to the injected nature of dependencies, you can take the advantage of certain existing services such as $HTTP service and reciprocate it with $httpBackend mock for testing. This gives actual results of the testing without depending upon the service.
Developing Single Page Applications has never been an easier task for developers, but thanks to AngularJS which makes this Herculean task a breeze. Using dependency injection function one can easily build apps that also grow on various services and modules. Angular makes it easy to organize these apps and also make them responsive enough to offer better experience to the users.
3. Impressive framework size
Page load time is a key factor that can easily make or break the success of your app. And since attention span is getting shorter with each passing day, it is highly essential to make sure your application does not behave in a rag tag manner. The size of a framework plays a crucial role in deciding its performance. The bigger the size, the more time a framework will take for bootstrapping. AngularJS minifiedgzipped version 1.2.22 boasts a size of 39.5KB, thus giving you complete power to build a flawless application efficiently.
Directives are the coolest feature of AngularJS and also the most useful one. Though it’s tricky to play around directives, but once you get the hang of them, it can do wonders for you as well as for your browsers. Directives are mainly used to create custom HTML tags that can be used to render custom widgets. They can also be used to style different elements with their respective behavior and manipulate DOM just the way you like.
5. Backed and promoted by Google
AngularJS is backed by a huge community of developers who are skilled and talented enough to build innovative web apps. In addition, those who take interest in the growth of AngularJS can contribute to this framework by submitting their valuable suggestions, developing more tools for it, and asking questions from the core team of Angular who will clear all your doubts in a comprehensive manner.
6. Fast and easy application categorization
Using AngularJS, it makes easy for you to categorize the application building blocks into multiple categories such as Controllers, Factories, Services, Directives, Templates etc. These categories are further divided into different modules. Each building block is provided with its own role. This implies that, Services are responsible for handling communication through backend, Views are for UI, and Directives will be responsible to make the process of building reusable components and also extend the HTML by assigning new attributes, elements, and behavior properties.
7. Dirty Checking feature
Angular comes with a really striking feature called Dirty Checking using which you don’t need to settle for getters and setters to access model data. You can do this by simply modifying the scope object. AngularJS automatically detects the change and inform others working on the property.
We have covered seven most prominent benefits of AngularJS. I hope having armed with such knowledge, you’d definitely like to goahead with Angular and make it a first choice while developing feature-rich web apps.
