| <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. |
