RxJS is considered advantageous in Angular development primarily because it simplifies the management of asynchronous data streams. In modern web applications, especially those built with Angular, handling asynchronous operations such as HTTP requests, user inputs, or WebSocket communication is crucial. RxJS provides a powerful library for composing and handling asynchronous events using observable sequences.

Observables in RxJS allow developers to work with streams of data effortlessly. They can listen to changes, handle multiple values over time, and manage complex event flows with operators that transform, filter, and combine streams. This gives developers greater control over asynchronous data, making it easier to manage side effects, cancel ongoing operations, and execute error handling.

The framework’s ability to work seamlessly with observables contributes to a reactive programming paradigm, where components can react to changes without worrying about the underlying implementation details. This leads to cleaner, more maintainable code and enhances the performance of Angular applications.

In contrast, the other options do not represent the core functionalities or advantages of RxJS within Angular development. For example, eliminating the need for observables is contradictory to the fundamental purpose of RxJS, while CSS animations and routing management fall outside its primary scope of handling asynchronous events and data streams.
