In Go development, function naming should follow a clear and concise convention: use Hungarian nomenclature or big/little camel case nomenclature, and avoid using underscores. Design principles include clarity, extensibility, composability, and simplicity. For example, a function that reads and parses a JSON file can be optimized to ReadAndParseJSONFile, following camelCase notation to clearly describe its functionality of both reading the file and parsing the JSON.
Go function naming convention and design principles
In Go development, it is crucial to use clear and concise function naming, because It reflects the readability, maintainability and scalability of the code. This article will explore the relationship between Go function naming conventions and design principles, and illustrate it through a practical case.

Practical case
Consider the following Go program, which provides a function for reading and parsing JSON data:
// readAndParseJSONFile reads and parses a JSON file. func readAndParseJSONFile(filePath string) (map[string]interface{}, error) { // ... }
According to Based on the above naming convention and design principles, we can optimize the function naming as follows:
// readAndParseJSONFile reads and parses a JSON file. func readAndParseJSONFile(filePath string) (map[string]interface{}, error) { // ... }
This improvement follows the following principles:
ReadAndParseJSONFile
and clearly describes its functionality, both reading a file and parsing JSON. readAndParse
is removed because the function name itself already describes these two operations. By adopting clear and concise function naming, we can improve the readability and maintainability of the code, making it easier for teamwork and future expansion.
