Go (often referred to as golang) is a programming language created at Google in 2009 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, limited structural typing, memory safety features and CSP-style concurrent programming features added. The compiler and other language tools originally developed by Google are all free and open source.. Read more on Wikipedia...

Example from Compiler Explorer:
// Type your code here, or load an example. // Your function name should start with a capital letter. package main func Square(x int) int { return x * x } func main() {}
Example from Riju:
package main import "fmt" func main() { fmt.Println("Hello, world!") }
Example from hello-world:
package main import "fmt" func main() { fmt.Println("Hello World") }
// Hello world in Go package main import "fmt" func main() { fmt.Printf("Hello World\n") }
Example from Linguist:
// Autogenerated by Thrift Compiler (1.0.0-dev) // DO NOT EDIT UNLESS YOU ARE SURE THAT YOU KNOW WHAT YOU ARE DOING package linguist import ( "bytes" "fmt" "" ) // (needed to ensure safety because of naive import list construction.) var _ = thrift.ZERO var _ = fmt.Printf var _ = bytes.Equal func init() { }
Example from Wikipedia:
package main import ( "fmt" "time" ) func readword(ch chan string) { fmt.Println("Type a word, then hit Enter.") var word string fmt.Scanf("%s", &word) ch <- word } func timeout(t chan bool) { time.Sleep(5 * time.Second) t <- true } func main() { t := make(chan bool) go timeout(t) ch := make(chan string) go readword(ch) select { case word := <-ch: fmt.Println("Received", word) case <-t: fmt.Println("Timeout.") } }
