You are working on a large codebase in Go. How would you organize your code to ensure modularity and ease of maintenance?

In Go, code organization is crucial for modularity and maintainability. Using packages to group related code files and separate concerns is the recommended approach. This promotes encapsulation, helps avoid naming conflicts, and makes code more readable and maintainable. Organizing code into folders without using packages doesn't provide the same level of isolation and maintainability. Placing all code in a single file or using global variables can lead to code that is hard to maintain and lacks separation of concerns.
