This is a creation in Article, where the information may have evolved or changed.

1. Variable parameters, incoming array of hungry time, must add three ... func sums (nums ...int) {}nums := []int{1, 2, 3, 4,  5}sums (Nums ...) 2. If the func  with the return value must be specified later in the return value type Func plus (a int, b int)  int {      return a + b}3. When using closures, the function name, the return value is the func ()   return value   format declaration func intseq ()   Func ()  int {     i := 0     return  Func ()  int {         i += 1          return i     }}4.  in Go, * flag a pointer,& The indicator points to a variable *PTRI&NBSP;:=&NBSP;&AMP;PTR5. The way to use in go, the more interesting place, the feeling is injected (yy) type user struct{     name} func  (u *user )  getName string{    return  U.name}func main () {    u := user{name: "Zhangsan"}&NBSP;&NBSP;&NBSP;&NBSp;fmt. Println (U.getname)}6. Use go  in go to do this self-execution (the first time the correct execution, the future has not been successful.) ) Go func (msg string)  {    fmt. PRINTLN (MSG)} ("Going") 7. Use channel  in go to use the go  keyword,make  can only be applied to Slice,map,channel8. <-chan   is ready to receive the sent value, chan<-is only receiving
