## Grammar
### Loops
```go
// for all condition
for {
fmt.Println("while true...")
}
// for keys/values in dict-like data
data := map[string]string{
"key": "value",
}
for key, value := range data {
fmt.Println("while true...")
}
```
### Enum
```go
// iota is enum keyword
const {
Unknown = iota // 0
Male = iota // 1
Female = iota // 2
}
// expression is as well supported
const {
Unknown = iota * 10 // 0
Male = iota * 10 // 10
Female = iota * 10 // 20
}
```
### Error
```go
if f, err := file.Open(path); err != nil {
return Response(400, err.Error())
}
if data, ok := json.Unmarshal(body); !ok {
return Response(400, "invalid json body")
}
```
### Goroutine
```go
func sendTemplate() {
// pyjy with wechat
}
func handleRequest(ctx Context) {
validate()
// sendTemplate()
go sendTemplate()
}
```
