so a simple a = b; will never copy a variable amount of data,
This is a simple, and therefore very common approach. Generally, most event systems, streams, and observables follow this rough pattern. Even promises/futures/async/await can be thought of as a one-time-only push-based reactive tree — each .then/.map/await call creates a listener to the previous step, and then when the initial promise resolves, the update is pushed through the rest of the system.。新收录的资料是该领域的重要参考

The second benefit is that we get dynamic dependencies for free. If pull-based reactivity is just a call stack, then it’s very easy to conditionally call (i.e. conditionally depend on) some input. We don’t need to maintain an internal list of which dependencies a node is subscribed to or vice versa, we just fetch values as needed.
