Application Performance Improvements :

Angular framework always focused on improving performance and the recent update is a strong testimony to that. Angular 7 is faster than all the other previously hurled Angular versions and the apps have an improved performance with the aid of the CDK module.
Recently, it was found out that most of the app developers were using reflect-metadata in their production, which really was not required in the development. Thus, to address the issue, Angular 7 automatically removes this from the polyfills.ts file.
Furthermore, all the new projects in the framework use Budget Bundles that instantly notify the developers when the app size reaches a certain limit. The default warning is given at 2MB and the error at 5MB.

Virtual scrolling

This feature allows dynamically loading or unloading the DOM components, depending upon their visibility. This leads to improved and faster performance for users who are dealing with large scrollable lists.
So, for potential large lists, the developers can simply stick in cdk-virtual-scroll-viewport component and benefit from the instant performance boost.

Ivy Renderer :

The Angular Ivy rendered still hasn’t been launched. The AngularJS development team has not yet disclosed a timeline and stated that the renderer is still under active development. However, as per an official blog report, the backward compatibility validation is under process and a complete beta version of the same is expected to launch with Angular 8. At the same time, some are expecting a soft launch of the Ivy renderer with the next Angular 7 version.
