Pull Request Overview
This PR improves the documentation about Map usage by clarifying what happens when using bracket notation (map[key]) instead of the proper Map methods. The update replaces a brief warning with a detailed explanation and concrete code example.
Key changes:
- Expanded explanation of why
map[key]should be avoided, clarifying that it adds properties to the Map object itself rather than storing data in the Map collection - Added a practical code example demonstrating the difference between bracket notation and proper Map methods
