RxJS Assessment Test

An RxJS Assessment Test evaluates candidates for their proficiency in RxJS, a reactive programming library for JavaScript. RxJS is widely used for handling asynchronous data streams and event-based programming in web applications.

An RxJS Assessment Test evaluates candidates for:

1. RxJS Fundamentals: Assessing candidates' understanding of basic RxJS concepts, including observables, observers, subscriptions, and operators.
2. Observable Creation: Testing candidates' ability to create observables from various data sources such as events, promises, arrays, or timers.
3. Operators: Evaluating candidates' knowledge of RxJS operators for transforming, filtering, combining, and manipulating data streams.
4. Subscription Management: Assessing candidates' proficiency in managing subscriptions, handling memory leaks, and unsubscribing from observables.
5. Error Handling: Testing candidates' ability to handle errors and exceptions within RxJS pipelines using error handling operators like catchError or retry.
6. Multicasting and Sharing: Evaluating candidates' understanding of multicasting and sharing observables to multicast data streams to multiple subscribers efficiently.
7. Schedulers: Assessing candidates' knowledge of schedulers in RxJS for controlling the concurrency and execution context of observable sequences.
8. Subject Types: Testing candidates' familiarity with different subject types in RxJS, including BehaviorSubject, ReplaySubject, and AsyncSubject, for sharing and broadcasting values.
9. Combining and Merging Streams: Evaluating candidates' ability to combine and merge multiple observables using operators like merge, concat, forkJoin, or combineLatest.
10. Testing and Debugging: Assessing candidates' proficiency in testing RxJS code using testing frameworks like Jasmine or Jest and debugging observable pipelines effectively.

Overall, our RxJS Assessment Test measures candidates' knowledge, coding skills, and ability to work with reactive programming concepts using RxJS, providing valuable insights into their proficiency in this area.
