Why can mixing Context Providers deeply inside rendering loops cause reconciler thrashing?

Expert React
Quick Answer Creating Context Providers inside rendering loops means each render creates new Context values and potentially new Provider component instances. This busts the Context value comparison, causing all consumers to re-render. Providers that recreate their value on every render of a parent cause "Context thrashing" รขโ‚ฌโ€ constant reconciler work for no real change.

Answer

Each Provider update invalidates all consumers; inside loops, this causes exponential rerenders.
