Go Version Manager (Multi Go)

GVM allow you to install and manage multiple Go version on a machine easily.

gvm stands for "Go Version Manager." It is a command-line tool that allows you to manage multiple versions of the Go programming language on your system. Go is known for its simplicity, performance, and efficiency in building scalable and concurrent applications. However, sometimes you might need to work with different versions of Go due to compatibility requirements or to test your code with different language versions.

gvm simplifies the process of installing, switching between, and managing multiple Go versions on your system. It provides an easy way to:

1. Install Different Versions: You can install various versions of Go side by side.

2. Switch Between Versions: gvm lets you switch between installed Go versions on demand, making it easy to work with different projects that might require different language versions.

3. Set Environment Variables: It automatically adjusts environment variables like GOROOT and PATH to ensure you're using the correct Go version.

4. Install Packages: You can install and manage packages for each version of Go independently.

5. Update Go: gvm can also help you update your installed Go versions.

Please note that while gvm is a convenient tool for managing multiple Go versions, there are other tools and methods available as well, such as manually installing Go versions or using other version managers. The specific choice depends on your preferences and needs.
