JavaScript best practices: readable code, const by default, avoiding globals, preferring ===, immutable patterns, proper error handling, modular code, and meaningful naming

- Prefer `const` unless reassignment is needed
- Avoid accidental globals and hidden mutation
- Good names and modules reduce cognitive load
