What are some practical use cases for observables in programming?
Observables are great for handling asynchronous data streams. Common use cases include UI updates, event handling, and data fetching.
Can you give me an example of how observables are used in a web application?
Sure! In a web app, observables can be used to manage user input events, like typing in a search box, and update the results in real-time.
What libraries or frameworks support observables?
Popular libraries include RxJS for JavaScript, and many frameworks like Angular have built-in support for observables.
Are there any performance considerations when using observables?
