What is the main purpose of a linter tool and why is it used in software development?

A linter is a static code analysis tool that checks source code for errors, potential bugs, style inconsistencies, and other issues without executing the program. Its main goal is to improve code quality, make it more readable and maintainable, and prevent errors early in the development process.

Using a linter helps to:

• Automatically find syntax and logical errors.
• Maintain a consistent coding style within the team.
• Reduce the number of bugs by identifying potential problems before code execution.

An example of using a linter in Go is golint or staticcheck.

golint ./...
