What methods can be used to evaluate the quality of written code?

The quality of software code can be assessed using the following methods:

• Static code analysis — using tools (e.g., golint, go vet, staticcheck) that check the code for style, potential errors, and adherence to best practices.
• Test coverage — measuring the percentage of code executed during tests. The higher the coverage, the better the code is tested.
• Code review — colleagues reviewing the code to identify errors, improve readability, and architecture.
• Code metrics — analyzing indicators such as function complexity (cyclomatic complexity), function length, number of lines of code, which helps assess maintainability.
• Performance testing and load testing — checking how efficient and resilient the code is under load.

Example of using golint:

golint ./...

This will output recommendations for style improvements and potential issues.
