In Go we don't have forEach keywords like JavaScript to loop through any collection instead, we use regular for with range keyword to work.

Example - 1

Regular Array looping

package main

import "fmt"

func main() {

    favMovies := []string{"inception", "intersteller", "tenant"}

    // for {key}, {value} := range {list}
    for _, movie := range favMovies {
        fmt.Println("My Fav movie is:", movie)
    }
}

Example - 2

Likewise, if we want to loop through the Hashmap (Objects in JS echo-system) -- we can do it in the same way.

package main

import "fmt"

func main() {

    myList := map[string]string{
        "dog":   "bark",
        "cat":   "meeeow",
        "lion":  "roar",
    }

    for animal, noise := range myList {
        fmt.Println("The", animal, "went", noise)
    }
}
