<h3>… simple</h3>

<pre class="code">
|
|
package main
|
|
|
|
import "fmt"

<h3>… 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>… 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>… 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—and say good-bye to stack overflows.
|
|
</p>
|
|
|
|
<h3>… 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.
