Answer
Separate business logic from UI, use modules/services for reusability, implement centralized state, optimize async behavior, avoid direct DOM manipulation, and follow consistent folder structure.
Quick Answer
Best practices for JS + frameworks: use TypeScript for type safety, follow framework conventions (hooks rules, OnPush, composition API), colocate component logic and template, avoid business logic in components (move to services/stores), write unit tests for services and integration tests for components, keep dependencies updated, and use framework-recommended patterns over clever workarounds.
