It is not only a source code repository, but also an important entrance to the Go compiler, runtime, standard library, tool chain, issue discussions and language proposals.</p> <p>If you just write business code, you may not necessarily read it every day; but if you want to understand why Go is designed this way, the official repository cannot be avoided.</p> <h2 id="whats-in-the-warehouse">What’s in the warehouse </h2><p>The official Go repository contains:</p> <ul> <li>Go compiler;</li> <li>runtime;</li> <li>Standard library;</li> <li><code>go</code> commands and toolchains;</li> <li>test and build scripts;</li> <li>issue and proposal discussion;</li> <li>release related changes.</li> </ul> <p>Many of the capabilities you usually use, such as goroutine, channel, GC, standard library network package, and module tool chain, can all be found here.</p> <h2 id="suitable-for-whom-to-watch">Suitable for whom to watch </h2><p>Suitable for these people:</p> <ul> <li>Go backend developer;</li> <li>People who want to understand Go runtime and scheduling;</li> <li>People who follow the evolution of Go versions;</li> <li>People who write high-performance services;</li> <li>People who do language, compiler or standard library research;</li> <li>People who encounter standard library boundary issues and need to check the implementation.</li> </ul> <p>It is not recommended to go through the entire warehouse from the beginning. You can start with standard library packages that you are familiar with, such as <code>net/http</code>, <code>context</code>, and <code>sync</code>.</p> <h2 id="learning-go-is-not-just-about-grammar">Learning Go is not just about grammar </h2><p>The core of Go is not the complexity of syntax, but the engineering trade-offs:</p> <ul> <li>Concise syntax;</li> <li>Strong standard library;</li> <li>Concurrency model;</li> <li>Quick build;</li> <li>Uniform format;</li> <li>Easy to deploy;</li> <li>Restraint in language evolution.</li> </ul> <p>Understanding these design trade-offs is more useful than memorizing the syntax.</p> <h2 id="summary">Summary </h2><p><code>golang/go</code> is the root of the Go ecosystem. Ordinary developers can use it as an entry point to check the behavior of the standard library, pay attention to version changes, and learn the runtime.</p> <p>If you have been writing Go for a while, occasionally reading the official source code will be more solid than just watching the tutorials.</p> <h2 id="reference-sources">Reference sources </h2><ul> <li><a class="link" href="https://github.com/golang/go" target="_blank" rel="noopener" >golang/go - GitHub</a></li> </ul>
