type switch

---

• A variable defined as an interface can get any type
• A switch statement can switch on the type of the variable

examples/switch-on-type/type_switch.go

package main

import (
    "fmt"
)

func main() {
    var x interface{}
    x = 1
    //x = "other"
    //x = 3.14
    switch x.(type) {
    case int:
        fmt.Println("int")
    case float64:
        fmt.Println("float64")
    default:
        fmt.Println("other")
    }

}

• multiple values in the same case
• tagless switch statement with real comparisions like x < 23 in the cases, here cases can overlap
• video
• fallthrough
• type switch
