C? test = (X() ?? Y()) ?? Z();
}
}
This code will output:
X()
X()
A to B (0)
X()
X()
A to B (0)
B to C (0)

This code proved it:

Select multiple records based on list of Id's with linq

Anyway the difference is significant. The fastest .Where .Contains is with Set<>. All it depends on complexity ...
Should flux stores, or actions (or both) touch external services?

This makes your store logic much easier to follow and very easy to test—just instantiate a store with some given state, send it an action, and check to see if the state changed as expected. Furthermore, one of the core concepts in flux is to prevent cascading dispatches and to prevent mult...
