Episode notes
Optional Chaining
- Use optional chaining (
?.) to safely access nested properties. - This avoids errors when properties are missing, simplifying data handling.
Promise.allSettled()
- Use
Promise.allSettled()to wait for all promises to resolve or reject. - Unlike
Promise.all(), it doesn't short-circuit on rejection.
Dynamic Import
- Employ dynamic imports for efficient module loading.
- This enables code splitting, loading modules only when needed.
