Idiomatic Go: Naming and Method Design

You will master the art of writing clear, idiomatic Go code by focusing on naming conventions and method design.

Writing clear and idiomatic APIs in Go is essential for maintainable and robust code. Go favors simplicity and readability, so follow these practical tips:

• Use short, descriptive names for methods and types; avoid unnecessary abbreviations;
• Prefer single-word method names for common actions, like Read, Write, or Close;
• Name interfaces based on behavior, using the "-er" suffix, such as Reader or Formatter;
• Export only what is necessary; keep implementation details unexported;
• Write method signatures that are concise and return errors explicitly;
• Document exported types and methods clearly with comments.

By following these guidelines, you create APIs that are easy to understand, use, and maintain.
