During the end of 2015, the AngularJS community publically announced the beta version of Angular 2. The changes were followed closely by the REST API development community. Angular is one of the most preferred frameworks for API developers to include a front-end to an API. The approach of Angular 2 is obviously less code and much better concepts. The framework leverages a component-based approach for achieving it. The syntax in related HTML templates has grown significantly. For sure, users of Angular 1 will make out a few concepts; however, there are a number of improvements to the execution.
What makes Angular 2 Different and More Preferable by the Developers?
It’s incredible Speed & Performance
Angular 2 is significantly much faster than Angular 1 along with the enhanced support for quick initial loads using server-side pre-rendering, offline assemble for quick startup, and ultrafast variation detection and analysis caching for easy effective scrolling and snappy view shifts.
Cross Platform
Developers are increasingly getting inclined to Angular 2 since it offers the tools required to build apps for mobile web, Android, and iOS and desktops. Angular Universal allows server-side interpreting for quick initial views, particularly on the mobile web. NativeScript and Ionic allow you build both native and hybrid UI mobile applications. Web worker support helps in keeping your application User interface completely responsive irrespective of the time taken to load.
Sensitive & Simple
Get successful at your objective using easy-to-write, natural syntax. Angular 2 helps in reducing the overall complexity for developers: new, structure-rich templates are easily readable and very quick to understand at a single look only.
Perfect Upgrade From Angular 1
Developers can easily upgrade their Angular 1 application at their own speed by integrating it in Angular 2 components, pipes, directives, services and others with the use of ngUpgrade APIs.
Flexible Development
Developers get the flexibility of choosing the language. Besides full support for Dart, ES5, and TypeScript, Angular 2 works perfectly well and with ease with ES2015 and other languages that work together with JavaScript.
Full Routing
Angular 2 has designed sophisticated views like they have map URL paths to app components, and utilize advanced features such as sibling and nested routes. Angular 2 is capable of supporting the animation transitions, card stack navigation, and sluggish loading for mobile users. If you’re already using routing from an outdated Angular version, you can quickly and effortlessly shift to Angular 2 routing.
Dependency Injection
The new Angular 2 works well with powerful, yet easy-to-use dependency injection, letting developers keep with the modular apps without writing down the boring copy-paste code. Dependency injection helps developers in writing tests by making it simpler to inject test doubles.
Legacy Browser Support
Beside the complete supporting latest versions of Firefox, Chrome, IE, Edge, and Safari, Angular 2 is even tested for outdated browsers including Android 4.1+ and IE9+.
Conclusion
The new changes and updates in Angular 2 offer developers several significant improvements. Since the concepts are considerably different from that of Angular 1, all the developers may be cautious in making the changes. Overall time and efforts invested in learning and knowing about the new ideas and actual structure of Angular 2 will surely be worthwhile.
