Creating new values

The reflect package allows us also to create new values using types. There are several functions that allow us to create a value:

• MakeChan creates a new channel value
• MakeFunc creates a new function value
• MakeMap and MakeMapWithSize creates a new map value
• MakeSlice creates a new slice value
• New creates a new pointer to the type
• NewAt creates a new pointer to the type using the selected address
• Zero creates a zero value of the selected type

The following code shows how to create new values in a couple of different ways:

func main() {
    t := reflect.TypeOf(int64(100))
    // zero value
    fmt.Printf("%#v\n", reflect.Zero(t))
    // pointer to int
    fmt.Printf("%#v\n", reflect.New(t))
}
