Sometimes developers have to rewrite the entire application code.Version 2.0 vs. Version 4.0Version 2.0 to 4.0 upgrade has reduced its bundled file size by 60%. The code generated is reduced and has accelerated the application development. Here the developed code can be used for production and debug mode.

JavaScript and TypeScript

Version 1.0 vs. Version 2.0Angular JS use JavaScript to build an application while on the other hand Angular v2.0 introduced the typescript to write the application. TypeScript is a superset of JavaScript which helps to build more robust and structured code.

This helps with better type checking and also enhanced IDE features for Visual Studio Code.

Mobile Support

Due to the use of Angular 2.0, native applications has been acquired for a mobile platform like React Native. Angular 2.0 provides application layer and the rendering layer. As a result, any view can be rendered in runtime for the required component.

It serves as a proper benefit by helping developers to divide the applications in terms of components with desired features and enable to call required UI. These features has increased the improvement in terms of the flexibility and re-usability as compared to Angular v1.0

SEO Friendly
