Answer from AI

The go.mod file in Go is used for dependency management and defining a module. It contains information about the module name, versions of used packages, and other settings related to dependency management. With go.mod, you can precisely lock library versions, ensuring reproducible builds and simplifying work with external packages.

Example content of go.mod:

module github.com/user/project

go 1.20

require (
    github.com/some/dependency v1.2.3
)

Thus, go.mod is the foundation of the module system in Go, replacing the old GOPATH system and making dependency management easier.
