  1. Svelte is a much better system for Observables. It requires setting up its dev tools. As it compiles observable code according to how it is being used.

    With rxjs, never ever use subscribe or unsubscribe yourself. Leave it to a framework such as Angular. Don’t put yourself in a place that a memory leak could happen. Even if it never does. Knockout.js deprecation is a good example why.

  2. Yes, this is something I agree with.
    Managing subscriptions ourselves can be risky because we might forget to unsubscribe from the Observable, resulting in a memory leak.

    Svelte manages our subscriptions on our behalf. This, in my opinion, makes it one of the most reactive frameworks.

    Considering Node.js where there are no native Observables, we are left to manage subscriptions ourselves.
