Best practices for function naming in Go

In the Go language, function names are important for program code readability and readability One of the key aspects of maintainability. Following best practices can improve team collaboration and avoid confusion caused by unclear function names.

Naming principles

• Use verbs or gerunds: Function names should clearly indicate their functions, using verbs or gerunds, For example GetUser, UpdateOrder.
• Be concise and to the point: Function names should be short and informative, avoiding redundant or ambiguous words. For example, GetUserDetails is better than GetUserInformation.
• Use consistent naming conventions: Follow consistent naming conventions across projects, such as letter case, prefixes, suffixes, etc.

Practical case

Suppose we have a function that verifies the format of an email.

Error example:

func ValidateMyEmail(email string) bool { ... }

• The name is ambiguous and does not clearly explain the function of the function.
• It uses the proper noun "MyEmail", which is unnecessary.

Best Practice:

func ValidateEmailFormat(email string) bool { ... }

• The name clearly indicates what the function does (validate email format).
• It uses a consistent naming convention, verb noun.
• It avoids redundancy and proper nouns.
