Check if an item exists in a slice in Go (Golang)

Let’s see a working code

package main

import "fmt"

func main() {
    source := []string{"san", "man", "tan"}
    result := find(source, "san")
    fmt.Printf("Item san found: %t\n", result)
    result = find(source, "can")
    fmt.Printf("Item san found: %t\n", result)
}

func find(source []string, value string) bool {
    for _, item := range source {
        if item == value {
            return true
        }
    }
    return false
}

Output:

Item san found: true
Item can found: false
