<h3>&hellip; simple</h3>
<pre class="code">
package main

import "fmt"

func main() {
  fmt.Printf("Hello, 世界\n")
}</pre>

<h3>&hellip; fast</h3>

<p>
Go compilers produce fast code fast. Typical builds take a fraction of a second yet the resulting programs run nearly as quickly as comparable C or C++ code.
</p>

<h3>&hellip; safe</h3>

<p>Go is type safe and memory safe. Go has pointers but no pointer arithmetic.
For random access, use slices, which know their limits.</p>

<h3>&hellip; concurrent</h3>

<p>
Go promotes writing systems and servers as sets of lightweight
communicating processes, called goroutines, with strong support from the language.
Run thousands of goroutines if you want&mdash;and say good-bye to stack overflows.
</p>

<h3>&hellip; fun</h3>

<p>
Go has fast builds, clean syntax, garbage collection,
methods for any type, and run-time reflection.
It feels like a dynamic language but has the speed and safety of a static language.
It's a joy to use.
