What is Feature-Sliced Design (FSD), how would you organize migration to FSD, and how would you resolve conflicts in layer interpretation?

Feature-Sliced Design (FSD) is an architectural approach to organizing frontend code based on dividing the application into independent features (functional areas), each containing its own layers (e.g., UI, logic, data). The goal is to improve scalability, maintainability, and reusability of the code.

To migrate to FSD:

1. Conduct an audit of the current structure and identify main functional areas.
2. Define feature boundaries and their layers.
3. Gradually reorganize the code by moving files into appropriate folders by features and layers.
4. Configure the build system and imports to support the new structure.
5. Implement standards and documentation for the team.

To resolve conflicts in layer interpretation:

• Organize discussions with the team to develop a common understanding.
• Create clear criteria and examples for what belongs to which layer.
• Use code reviews to ensure compliance with rules.
• If necessary, adapt the structure to the project's real needs while maintaining FSD principles.

This approach helps avoid misunderstandings and maintain architecture in a consistent style.
