Using govet
The govet tool is a static analysis tool without running code that can help you find potential issues in your Go code.
govet checks your code for all sorts of problems that could cause bugs or lead to poor performance. It's like a code quality police, constantly checking to make sure you're not doing anything stupid.
To use govet, you can run the go tool vet command and pass the names of the Go source files you want to check as arguments:
go tool vet main.go
