Why Choose Go (Golang) for Backend Development and How to Install It
This article introduces Go (Golang), explains its key advantages for building high‑availability, scalable backend services, and provides step‑by‑step installation instructions for macOS, Windows, and Linux platforms.
1. What is Golang?
Go, also known as Golang (the official website uses golang.org), is an open‑source compiled static language developed by Google.
Go’s primary focus is to make the development of highly available and scalable web applications simple, although it is fundamentally a systems programming language with strong support for web development.
2. Why Choose Golang?
Although many other languages such as Python, Ruby, and Node.js can perform similar tasks, Go offers several distinct advantages:
Concurrency is built into the language (not just a library), making multithreaded programming straightforward via goroutines and channels.
Go is a compiled language; source code is compiled to native machine code, unlike interpreted languages such as JavaScript in Node.js.
The language specification is concise and all documented on a single page, even allowing you to write your own compiler.
The Go compiler supports static linking, producing a single binary that can be easily deployed to cloud servers without worrying about dependencies.
3. Installation
Go supports macOS, Windows, and Linux (and other major platforms). Binaries can be downloaded from https://golang.org/dl/ (or alternative mirrors if needed).
Mac OS
Download the installer from https://golang.org/dl/ , run it, and follow the prompts. Go will be installed to /usr/local/go and /usr/local/go/bin will be added to your PATH.
Windows
Download the MSI installer from https://golang.org/dl/ , run it, and follow the prompts. Go will be installed to C:\Go and C:\Go\bin will be added to your PATH.
Linux
Download the tar archive from https://golang.org/dl/ , extract it to /usr/local, and add /usr/local/go/bin to your PATH. Go will then be ready to use.
In the next part of this series, "Golang Tutorial Part 2: Hello World," we will set up a Go workspace and write our first Go program.
