a systems programming language
expressive, concurrent, garbage-collected |
Go is …
… simple
package main
import "fmt"
func main() {
fmt.Printf("Hello, 世界\n")
}
… fast
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.
… safe
Go is type safe and memory safe. Go has pointers but no pointer arithmetic. For random access, use slices, which know their limits.
… concurrent
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.
… fun
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.
