Each version of Angular has significant benefits but it is always recommended to be up to date with the recent stable version because Angular is impeccably faster than Angular JS and has a mobile-driven approach. Angular allows smoother migration from earlier versions, executes better with Components and Directives. Angular JS is still being efficiently used by many companies rather than the updated versions of Angular.

How Angular is different from AngularJS?

• AngularJS is based on Model-View-Controller (MVC) design architecture. Whereas in Angular, controllers and $scope were replaced by Components and Directives.
• AngularJS is written in JavaScript. Whereas Angular is written in TypeScript.

Consider the two-way binding feature in terms of speed and performance, AngularJS takes more time in page loading. Angular allows a better structure to easily create and maintain big applications and thus optimizing the performance.

Glimpse on the all new Angular 6

In May 2018, Angular Team has released Angular 6.  For me, Angular is always exciting for developing Single page applications. I’m going to discuss a few of the interesting features of Angular 6 below.

ng update

ng update <package> is a new CLI command which updates your application specific packages and frameworks. It automatically adopts the correct version of dependencies and keeps your dependencies in sync. For instance, ng update @angular/core command will update all of the Angular framework packages as well as RxJS and TypeScript.

ng add

ng add <package> command helps you add new packages to your project very easily. For example, ng add @angular/material installs Angular Material and its theme into your application.

Greater Vision of Future: ngIvy

Most of the resources involved in the implementation of Angular 6 have gone into a very innovative concept: The new view engine ngIvy. It compiles Angular templates to very DOM-like code and is optimized for Tree Shaking. This means that only those parts of Angular which are actually needed are bundled.

The best thing about ngIvy is that application developers should not notice this, except for the smaller bundle sizes. It is a replacement of an implementation under the bonnet. This backward compatibility is targeted for one of the next Angular versions. Until then ngIvy is an experimental feature.

Tree Shaking Providers

Previous versions of Angular followed Modules referencing Services. In Angular 6, we will be having Services referencing Modules which allows to only bundle services into the code base in modules when they are injected. Tree Shaking is one step in the build process that eliminates unused code from the code base. This way, we can make sure our application includes only the code which is needed and thus optimizing the performance of the application.

In case, if you are you planning to upgrade your existing Angular application to Angular 6? Here is the Angular Update Guide which is made available by Angular Team on their website. It has all the steps to follow before updating, during update, and after updating.

Future releases

The beta version of Angular 7 has already been released in August 2018 and the stable version of it might be released in October 2018.
