Curious about its new features and updates! We have all the big details here, right in front of you. Before knowing all the other details, please we will start with basic knowledge about angular lifecycle.
Angular is used to build web and mobile applications, as it is one of the most popular Javascript frameworks. It has received a warm acknowledgment from the development community. Till date, there are six stable versions of Angular framework which are released – Angular 1 (also known as Angular JS), which is followed by Angular 2 and Angular 4 again followed by Angular framework’s version 5 and 6. The release of the Angular framework’s version 3 which was skipped by Google as there were some issues and problems with the modules.

In production, the reflect-metadata polyfill is included which is required in the development. When you build your application in JIT(Just-In-Time) mode, then as a part of the update it will automatically remove a polyfills.ts file. It will make the application smaller.
5) Angular Elements
