Disposing Observables
Explore how to unsubscribe from RxJS Observables to efficiently manage resources and avoid memory leaks in single-page applications. Understand the process of disposing Observables during long-running operations like HTTP requests or intervals, ensuring better control over asynchronous code execution.
We'll cover the following...
In the previous sections, you were able to see how powerful Observables really are. But hang on, there is more.
Contrary to promises, which serve as a one-time shot, Observables run once they are created, and that’s it.
Imagine if we created a promise for an HTTP call that took too long to respond or didn’t respond at all, and we navigated to another page in the meantime. What would happen to the memory in this case? You may think that JavaScript garbage collector will handle it, but for single page applications, that’s not really the ...
