Introduction to angular js
AngularJS on the other hand is a structural frame work for adding client side dynamic features to web applications. To me, it lets developers turn HTML into a template language and extend HTML’s syntax to allow for precise, concise descriptions of application components; you can write your application logic in JavaScript but you define the view using HTML. In this tutorial you will get to learn the introduction Angular Js; what it is, how it operates, its strengths, and its weaknesses.
Key features
Model-View-Controller (MVC) architecture: AngularJS encourages selecting problems by splitting the utility into three combined Components: model (records), View, and Controller (logic).
Data Binding: AngularJS helps utilizing $scope variable and robotically synchronize information with the model and the view. All changes are made to the model are effecting the view and vice versa.
Dependency Injection: AngularJS deals with object creation and control of dependency, that makes the code more testable and maintainable.
Directives: new attributes or nodes that are not part of HTML but are defined by putting an identifier before a hyphen.
Templating: Can create appealing views on the go with the use of HTML templates.
Routing: Controls switching between isolated views of a SPA located within a single page.
RESTful API support: it also allows easy interfacing with RESTful web services.
How it Works
HTML structure: describe the structure of your software and the use of html including angular js directives.
JavaScript logic: Use JavaScript to perform application processing and developing controllers and models.
Data Binding: This is good since AngularJS works by automatically synchronizing facts between the model and the view.
Dependency Injection: AngularJS handles the requirements and passes them into additives.
Directives: enhance HTML with its own made elements and attributes.
Routing: Handles moving from one view to another.
Advantages
Increased development speed: Statistic show that binding and dependency injection have greatly minimize development time.
improved Code Testability: The MVC and dependency injection contribute to testing.
enhanced user Experience: Clean and responsive consumer enjoyment is provided by SPAs.
large and active Community: availability of lot of help and resource .
Cross-browser Compatibility: AngularJS deals with move-browser problems.
Disadvantages
Steeper learning Curve: Compared to different frameworks, mastering AngularJS will be necessarily more difficult.
performance Overhead: May cause overall performance overhead when dealing with complex program.
Digestive Complexity: AngularJS’s digest cycle might not be easy to understand.
Summary
It is a great tool for building new generation dynamic web sites. It provides capabilities for data binding, dependency injection and directives, which make development much easier. Though it has some learning curve problems and troubles on the ability performance, in terms of the development speed, testability and user experience, it wins lots of developers’ favor.
Notice: AngularJS is still used in new projects due to its dependence in many projects but Angular or Angular 2+ as it is commonly called is the recommended version for new projects. This one provides better performance, the concept of modularity and element-based structure.
