In the JavaScript ecosystem, it is still popular, in modern times, for developers to spend their time manually creating and maintaining project build files. Being a modern programming language, Go ships with an implicit build system.

As long as you follow Go's prescribed conventions, and once you issue the go build command for your Go application, the implicit build system kicks in. It will build and compile the Go project automatically by examining the dependencies it finds, within the application's Go source code itself. This provides a major productivity boost for the developer.
