This is a new object data type. It also has extensions to the event interface. It was discussed at the most recent TPAC. Chrome has an implementation for evaluation.

The proposal is very complicated, so this will need some time to consider. For example, which all problems will microtask scheduled event handling cause. And does it solve the problems we want to solve.

[domfarolino]

Thanks for the reply. Just to note, the microtask "issue" is only relevant for the Promise-returning operators: https://wicg.github.io/observable/#promise-returning-operators.

To aid your analysis on this portion of the proposal, it would probably be useful to check out some of the previous discussion where we detail why this shouldn't be much of an issue at all, and why it makes sense (there are a lot of issues/threads so I wanted to just surgically point you to some of the most relevant discussion on that topic in particular).

However I'll note that nothing is set in stone yet, so we'd love more engagement on this if you or other have strong opinions one way or another, to help shape this API surface.
