Ran 2024-04-09 on a MBP M1.
We created 10,000 selectors that return the same static value. Currently, we have ~1k instances of useState in browser. We can pretend that corresponds to 1k places state is needed and selectors created if it were all in redux (which we'd never do, this is for understanding orders of magnitude). Then we 10x that for an arbitrary buffer of codebase growth.
Render time per state change: 8ms
Without any extra selectors: 1ms
Used the same number of "selectors", creating pieces of observable state on the counter store.
Render time per state change: 0.9ms
Run with npm start.
For prod build, do npm run build, then run
npx serve -s build
