Go Basics

Note

First go to the folder where the go file is present.

• To run a go application in development :

   go run firstCode.go

• In production :

   
   # initialize the module (on MacOS)
   go mod init /path/to/your/goFile/customModuleName
   # build the module
   go build 
   # Run the module and get the executable file (on MacOS)
   ./customModuleName

• Go has modules and each module has multiple packages
• Should have atleast one package in a file
• A single package can be split accross multiple go files
• Can have multiple packages in one go file also
• Go standard libraby for packages
