What are the best practices for using observable patterns in programming?

The observable pattern is great for managing state and events. Key practices include keeping observables simple, using operators wisely, and ensuring proper cleanup.

Can you explain how to implement observables in JavaScript?

Sure! In JavaScript, you can use libraries like RxJS. Start by creating an observable using new Observable(), then subscribe to it to receive updates.

What are some common pitfalls to avoid when using observables?

Common pitfalls include memory leaks from not unsubscribing, overusing observables for simple tasks, and not handling errors properly.

How do observables compare to promises?

Observables can handle multiple values over time, while promises handle a single value. Observables are more powerful for event streams.

Can you give an example of a real-world application of the observable pattern?

Certainly! A common example is in UI frameworks where observables can be used to manage state changes and update the UI reactively.
