Redux Ecosystem
Why does Immer's confirmed structural sharing matter for useSelector and createSelector from the Selectors & Reselect topic?
A
It doesn't matter, they work independently of this
B
Both rely on reference-equality comparisons to decide whether to re-render/recompute — structural sharing is what keeps untouched branches' references stable so those optimizations actually work
C
It only matters for TypeScript type-checking
D
createSelector requires structural sharing to function at all, or it crashes
