How to manage dependencies in Go?

Go provides a built-in package management system called "modules" that makes it easy to manage dependencies in your Go projects. 

Here's an overview of how to use modules in Go:

Initialize a module: To start using modules in your project, you first need to initialize a new module by running the **go mod init** command. For example, if you want to create a new module called "myproject", you would run:

go mod init myproject

This command creates a new **go.mod** file in your project directory, which lists your module's dependencies.

Add dependencies: To add a new dependency to your module, you can use the **go get** command. For example, to add the popular **gorilla/mux** router package to your project, you would run:

go get github.com/gorilla/mux

This command downloads the **gorilla/mux** package and adds it to your module's dependencies.

Use dependencies: Once you've added a dependency to your module, you can use it in your code like any other Go package. For example, if you want to use the **gorilla/mux** router in your project, you would import it in your code like this:

import "github.com/gorilla/mux"

Update dependencies: To update your module's dependencies to the latest versions, you can use the **go get -u** command. For example, to update all of your module's dependencies to their latest versions, you would run:

go get -u ./...

This command updates all of the packages in your module's **go.mod** file to their latest versions.

Overall, Go's module system provides a simple and powerful way to manage dependencies in your projects, allowing you to easily add, remove, and update packages as needed.
