Architecture, immutability and performance

0%

Choosing a state management library is only part of the architecture. This stage is about which layer state belongs to, how immutability ties into performance, and how rebuilds are controlled — where most senior interview questions come from.

1. The official architecture: which layer state lives in

3. Dependency injection and testability
