It is an open source project developed by Google and is popular for its extremely high performance and ease of use. So, how to quickly install Golang and use it? The following will introduce you to the Golang installation tutorial and provide corresponding code examples.
1. Install Golang

Run the following command on the command line to print out "Hello, world!":
go run hello.go
Through the above operations, you have successfully installed and used Golang and can use Golang for programming development. If you need to learn more about Golang, you can further learn Golang's syntax and the use of related libraries.
