Angular 16 is a major release that includes a number of new features and improvements. Here are some of the key features of Angular 16:
- New reactivity model: Angular 16 introduces a new reactivity model that is based on RxJS. This new model provides a number of benefits, including improved performance, better error handling, and more flexibility.
- Optional Zone.js: Angular 16 makes Zone.js optional. Zone.js is a library that provides a number of features for Angular applications, such as event handling and change detection. However, it can also add some overhead to applications. By making Zone.js optional, Angular developers can choose whether or not to use it, depending on their specific needs.
- New DestroyRef provider: Angular 16 introduces a new provider called DestroyRef. This provider can be used to register destroy callbacks for a specific lifecycle scope. This can be useful for cleanup tasks that must be performed when a component is destroyed.
- Improved Router: Angular 16 includes a number of improvements to the Router, including the ability to bind Router information to component inputs and the ability to use the takeUntilDestroyed() pipe to automatically unsubscribe from an observable when a component or directive is destroyed.
- Design tokens in Angular Material Library: Angular Material Library now includes support for design tokens. This makes it easier to customize the look and feel of Angular Material applications.
New Reactivity Model
The new reactivity model in Angular 16 is based on RxJS. This means that Angular applications now use RxJS to track changes to data and trigger change detection. This new model provides a number of benefits, including improved performance, better error handling, and more flexibility.

Here are some additional details about the new features in Angular 16:
New reactivity model: The new reactivity model in Angular 16 is based on RxJS. This means that Angular applications now use RxJS to track changes to data and trigger change detection. This new model provides a number of benefits, including improved performance, better error handling, and more flexibility.
RxJS is a library that provides a number of features for managing asynchronous data. It is based on the concept of observables, which are sequences of values that can be emitted over time. Observables can be used to represent a wide variety of data sources, including events, network requests, and timers.
Angular applications that use the new reactivity model will benefit from a number of improvements, including:
- Improved performance: RxJS provides a number of optimizations that can improve the performance of Angular applications.
- Better error handling: RxJS provides a number of ways to handle errors that occur during data processing.
- More flexibility: RxJS provides a number of ways to customize the way that data is processed.
Optional Zone.js: Zone.js is a library that provides a number of features for Angular applications, such as event handling and change detection. However, it can also add some overhead to applications. By making Zone.js optional, Angular developers can choose whether or not to use it, depending on their specific needs.
**Zone.js is a library that monkey-patches the JavaScript runtime to provide a number of features, such as event handling and change detection. While this makes Angular easy to use and write, it also adds some overhead and complexity to the framework. In Angular 16, Zone.js will be optional, meaning developers can opt out of it and use other ways of managing reactivity, such as RxJS or signals.

Observables can be used to represent a wide variety of data sources, including events, network requests, and timers.
Signals are a new feature in Angular 16 that are based on RxJS observables. Signals provide a number of benefits, including:
- Improved performance: Signals are more efficient than traditional change detection mechanisms.
- Better error handling: Signals provide a more robust way to handle errors.
- More flexibility: Signals provide more ways to customize the way that data is processed.
Angular applications that use signals will benefit from a number of improvements, including:
- Improved performance: Signals are more efficient than traditional change detection mechanisms.
- Better error handling: Signals provide a more robust way to handle errors.
- More flexibility: Signals provide more ways to customize the way that data is processed.
In addition to the new reactivity model and optional Zone.js, Angular 16 also includes a number of other improvements, including:
- Improved Router: Angular 16 includes a number of improvements to the Router, including the ability to bind Router information to component inputs and the ability to use the takeUntilDestroyed() pipe to automatically unsubscribe from an observable when a component or directive is destroyed.
- Design tokens in Angular Material Library: Angular Material Library now includes support for design tokens. This makes it easier to customize the look and feel of Angular Material applications.
