What’s New In Angular 9?

Angular 9’s most prominent new feature is Ivy. Ivy is Angular’s new compiler and renderer. The renderer is the engine that takes your components and templates and translates them into instructions that manipulate the DOM. Ivy is an internal component, so you don’t interact with it directly. However, it can have a significant impact on your code, yielding much smaller JavaScript bundles and increasing performance.
Read more about Angular Ivy at https://angular.io/guide/ivy.
Here is the summary of Angular 9 features:
  • Smaller bundles and better performance.
  • The Ivy compiler: The default use of the Ivy compiler is the most important feature of Angular 9, Ivy is what actually designed to solve the major problems of Angular i.e the performance and large file size.
  • Selector-less bindings support for Angular Ivy.
  • Internationalization support for Angular Ivy.
  • Support for TypeScript Diagnostics Format.
  • Support for more scopes in providedIn
  • A New Type-Safe TestBed.inject() Method Instead of TestBed.get()
