Angular Interview Practice

Angular heavily relies on RxJS for handling asynchronous operations due to its powerful capability to work with streams of data, allowing developers to easily manage events and handle them reactively. RxJS provides a wide array of operators and utilities that facilitate complex asynchronous programming models, including the handling of multiple values over time, which is particularly useful for scenarios like HTTP requests, user input events, and other asynchronous tasks.

Observables in RxJS enable Angular applications to respond to changes in data or input in a very efficient way. They allow for composing asynchronous operations with ease, and their support for combining multiple streams of data is particularly advantageous in building reactive interfaces. This aligns seamlessly with Angular's architecture, which promotes the use of reactive programming paradigms to handle state changes and side effects effectively.

In contrast, while Promise.js and Async/Await are also methods for handling asynchronous operations in JavaScript, they do not offer the same level of flexibility and composition capabilities that Observables provide. They are more suited for handling single asynchronous events rather than complex data flows, which is essential in many Angular applications. Observable.js, on the other hand, is not a recognized standard library used by Angular.
