Overview
Strict mode is a set of independent flags. Knowing what each one catches lets you adopt them incrementally on an existing codebase.
In this lesson you will:
- Understand what each strict flag actually checks
- Turn on strictness incrementally in a legacy project
- Configure module resolution to match your runtime
Pro Tip
Use caching and revalidation wisely to ensure your app stays fast and data remains fresh without unnecessary requests.
