How to avoid being too specific or too abstract in golang function naming?

To avoid function names that are too specific or abstract, follow these best practices: Descriptive: Function names should accurately describe their functionality without using technical details. Concise: Keep it as short as possible but still convey the meaning of the function. Readable: easy to read and understand.

Go function naming: avoid being too specific or abstract

The naming of functions in the Go language is crucial because it not only Helps improve code readability and maintainability, and ensures functions are easy to understand and reuse. However, when naming functions, you should avoid being too specific as well as being too abstract.

Overly specific function names

Overly specific function names will limit the scope of the function to a specific scenario, making it unsuitable for other similar use cases . For example:

func calculateMonthlyPayment(loanAmount float64, interestRate float64, loanTerm int) float64

This function name is very specific, clearly stating that it calculates the monthly payment of a mortgage loan. This function cannot be reused if payments need to be calculated for other types of loans.

Overly abstract function names

On the contrary, too abstract function names will make the function of the function unclear and difficult to understand its purpose. For example:

func doSomething(arg1 any, arg2 any) any

This function name is unclear and does not provide any information about the actual purpose of the function.

Best Practices

The ideal function name should have the following characteristics:

• Descriptive: It should Describe exactly what the function does without using technical details.
• Conciseness: Keep it as short as possible but still convey the meaning of the function.
• Readable: Easy to read and understand.

Practical case

The following example shows how to choose an appropriate name for a function:

Too specific:

func calculateMonthlyMortgagePayment(loanAmount float64, interestRate float64, loanTerm int) float64

Transitional Abstract:

func calculatePayment(arg1 any, arg2 any) any

Best:

func CalculateLoanPayment(loanAmount float64, interestRate float64, loanTerm int, loanType string) float64

This name is descriptive and concise, clearly stating the What this function does: Calculate payments for a specified type of loan.

By following these best practices, you can create functions with clear and maintainable names, making your Go code easier to understand and reuse.
