How is golang free?

1. Background introduction

In recent years, open source and free software have become a mainstream trend in the technology industry, including many open source and free software in fields such as cloud computing, web development, and mobile application development. tool. Among these tools, the open source programming language Golang has received widespread attention and application due to its excellent performance, efficient language structure and rich ecosystem.

Golang was originally designed and developed in 2007 by three developers from Google, Robert Griesemer, Rob Pike and Ken Thompson. Its goal is to solve some problems existing in the C language and keep it simple and easy to use. and maintainability features. This goal makes Golang an excellent tool for web applications, network services, and large-scale data processing.

2. The free nature of Golang

Golang is a free programming language that can not only be used for commercial purposes, but also can be used on any platform and operating system. The open source nature of Golang makes it a common asset for developers and organizations around the world. People can make full use of Golang's features in their own engineering projects without paying any fees.

Golang’s open source license is the BSD license, which is a license that allows developers to freely use, change and redistribute Golang code. This agreement allows developers to make a contribution to the Golang community while also being rewarded in terms of revenue, growth and innovation. A further benefit is that developers can use and improve other open source Golang code because the protocol opens Golang to the entire community.

For Golang users and developers, this means that they can access and use other open source tools and libraries through Golang to achieve higher efficiency and faster development. These open source tools and libraries are also free. They provide comprehensive and powerful functions to facilitate Golang users to quickly implement complex tasks during the development process.

3. How to use Golang

To use Golang, you first need to download the Golang installation package. You can find the installation package for your operating system on the Golang official website (https://golang.org) and download it. After the download is complete, you only need to install Golang according to the official documentation. Once the installation is complete, you can start trying to write Golang programs.

Writing a Golang program is easy, just open a new file using your favorite text editor and write your code. Golang's coding style requires the use of tab keys or space keys for code indentation, making the code structure clear and easy to understand. After the code is written, you only need to use the command go run filename.go in the terminal window to run the program.

When using Golang for program development, you can use a variety of different open source libraries, which can be found on GitHub. The advantage of using these open source libraries is that they encapsulate commonly used functions in a conventional way, making tedious tasks simple and efficient.

In short, Golang is a free programming language and a very practical programming tool. Through Golang, developers can quickly and easily write high-performance programs, and can make full use of Golang's rich open source libraries to simplify programming tasks.
