useSubscription and useMutableSource¹ tearing and deopt behavior.

Mounting a new tree

The tree below represents a React application mounting. During mount, two components read from an external, mutable source. The first one (List) reads version 1 of that data and the second one (Item) reads version 2.

When it comes to memo'ization any option will be valid if it meets the following three criteria.

1. Will this work be closer to the root, or the leaf?

As we approach the leaves of the component tree the impact of memo'ization will be diminished as the number of impacted children decreases.

As the number of potential children increases we offer a corresponding level of care in making sure our values only update when there's a pertinent change to that value.

2. Where will my work be used?
