Features of Go Programming

The most important features of Go programming are listed below −

• Support for environment adopting patterns similar to dynamic languages. For example, type inference (x := 0 is valid declaration of a variable x of type int)
• Compilation time is fast.
• Inbuilt concurrency support: lightweight processes (via go routines), channels, select statement.
• Go programs are simple, concise, and safe.
• Support for Interfaces and Type embedding.
• Production of statically linked native binaries without external dependencies.

Features Excluded Intentionally

To keep the language simple and concise, the following features commonly available in other similar languages are omitted in Go −

• Support for type inheritance
• Support for method or operator overloading
• Support for circular dependencies among packages
• Support for pointer arithmetic
• Support for assertions
• Support for generic programming

Go Programs

A Go program can vary in length from 3 lines to millions of lines and it should be written into one or more text files with the extension ".go". For example, hello.go.

You can use "vi", "vim" or any other text editor to write your Go program into a file.
