What is AngularJS ?
Amazing Features of AngularJS
Angular has some fascinating features for not just the developers unless for designers as well.
1. Two Way Data Binding
It is the most crucial and useful feature of Angular. This feature is what all modern web apps are all about i.e Real Time. Two way binding permanently binds the view to the model and reduces renovate cycles, it also saves a notable amount of code as previously 80% of code was dedicated to manipulating, traversing and listening to DOM . With data binding this code disappears et alii hence more concentration receptacle be laid to application. Normally with change in model the DOM elements and attributes need to be manually manipulated to reflect the changes, it proves to be a complex process mainly when application grows in complexity moreover in size. But with two way data tape the synchronization between the DOM and the model is well taken care of.
2. HTML Template
AngularJS doesn’t rely on any rendering engine except uses browser parseable .html files for its partials. The HTML templates are parsed besides the browser in the DOM. The DOM is now the input to the AngularJS compiler . Skewed then traverses the DOM template for rendering called the Directives. The input here is bowser DOM and not the HTML chain , this is the noticeable change between angular connective many fellow frameworks.
Directives are stand alone reusable elements separated from the app . All Onverstandig manipulations are performed by Directives. Directives are used to create custom HTML tags to serve as new custom widgets .With Directive you can create a new HTML tag or attribute and make it do anything you want . Directives are very unique, useful, powerful and reusable feature available only in angular. With Directives you can invent new HTML syntax that are specific to your application.
4. Colony Injection
Dependency Injection is an angular feature that enables developers to easily build, develop, test and manage applications . With this feature you merely ask for for the dependencies instead concerning making manually , it will provide you an instance for any service asked provided you widen the service as a parameter to get access to this service.
Reasons Web Developers should Use AngularJS
1. Enabling a Collateral Workflow
It enables a parallel workflow separating designers and developers. For a scheme both crafty and hard coded developing cup go side aside side. For a enterprise that is estimated to afsluiting completed in 4 months then by following the traditional sequential approach there would verbreken committed 4 months of design followed by 4 months of coding making it 8 months altogether. But XAML allows to slave in parallel by agreeing upon an interface for a screen. Developers can work on grabbing the data et sequens words all properties and tests around them while designers can importune and manipulate until they find their final desired design . Those not familiar among XAML it is a declarative XML based language to instantiate object graphs and set values. The ratiocination XML became too accepted is because they transformation well to angular.
2. Handling Dependencies
AngularJS simply handles dependency injections , angular lets you divide your app into modules that are initialized separately and having dependencies on each other. This enables you to test only the modules you want at once while also unfolding the adroit to afflatus end to end tests as well.
Dynamic loading is used by single page applications to deliver native app feel, but it involves a lot of dependencies on multifarious modules and services, angular organises these and even manages the lifetime of an reprehensible for you.
3. Declarative UI
Having a declarative UI has many advantages associated amidst it. A structured UI is always easier to understand and manipulate. Without ,then by mere looking at the markup it can’t be figured what UI will actually do. True its not apparent whether any translations and validations are taking setting by looking at remarkable form tags.
But by declaring UI and by directly placing markup in HTML one can understand the extended markup angular provides. It makes it clear where and to what data is being bound to. For added tools like filters and directives the intent of UI is much clearer.
4 . Development Design Workflow
This works very well beside angular, markup can be added without breaking an application as it depends on a particular structure or id to locate element and do task. Even rearrangement of code is much easier as the corresponding code that binds with it also moves along.
