Redux Ecosystem
Why does keeping individual reducer functions cheap matter for performance, given how dispatch works?
A
It doesn't matter, reducers only run for relevant actions
B
combineReducers fans out every dispatched action to every slice reducer, so every reducer runs on every single action dispatched anywhere in the app
C
Reducers run on a background thread, so cost is irrelevant
D
Only the first reducer defined ever executes
