Welcome to the start of our new series about the Go programming language. Go is a modern, simple, and fast programming language that is compiled, open-source, and strongly typed. It was developed by Google engineers with the goal of making projects compile and run faster, being easy to learn, avoiding common low-level pitfalls, offering portability, stability, and predictability, and taking advantage of multiprocessor systems. Go is designed to be a replacement for C and C++, but it also works well with existing C and C++ codebases through its C interoperability features. It can be used for a variety of needs, from creating command line utilities to building networking servers, and it is widely used in many different scenarios. In fact, popular tools such as Docker, Kubernetes, Hugo, and Caddy are all written in Go.
To get started with Go, visit the official homepage of the language at https://go.dev. Here, you can download the Go binaries, access the official documentation, explore the available Go packages, and even try out the Go Playground. Make sure to download and install the package for your operating system and verify the installation by running the go version command in your terminal.
To enhance your Go development experience, I recommend using VS Code (Visual Studio Code) as your editor. You can quickly set up VS Code for Go development by following the instructions in the “Go in VS Code” documentation. Install the Go extension to benefit from features such as IntelliSense, syntax highlighting, autocompletion, error highlighting, code formatting, and more. For added convenience, enable the “Format on Save” and “Format on Paste” options in the VS Code settings.
When working with Go code, comments can be added using the typical C/C++/JavaScript/Java syntax. Line comments start with //, while multi-line comments can be enclosed in /* */. Unlike Python, Go does not rely on semantically significant whitespace and allows for optional semicolons, similar to JavaScript. However, Go places importance on indentation and visual order, which is enforced by the gofmt command line tool. This tool, also used by VS Code, ensures consistent and standardized formatting across different Go projects, saving developers valuable time and avoiding debates over coding style.
In the upcoming days, we will delve into the specifics of the Go programming language and introduce new concepts. Stay tuned for more!
