Go Switch

The switch statement allows us to execute one code block among many alternatives.

You can do the same thing with the if...else..if ladder. However, the syntax of the switch statement is much easier to read and write.

Switch statements express conditionals across many branches.

Syntax of Go Switch

switch expression {
case x:
   // code block
case y:
   // code block
case z:
...
default:
   // code block
}

Example of Go Switch

package main

import (
    "fmt"
    "time"
)
func main() {

    i := 2

    switch i {
    case 1:
        fmt.Println("one")
    case 2:
        fmt.Println("two")
    case 3:
        fmt.Println("three")
    }
}

Output

two

Example of Go Switch With default

package main

import (
    "fmt"
    "time"
)
func main() {

    i := 4

    switch i {
    case 1:
        fmt.Println("one")
    case 2:
        fmt.Println("two")
    case 3:
        fmt.Println("three")
    default:
     fmt.Println("Not available")
    }
}

Output

Not available
