map Get value in Go

In Go, to get the value of a specific key in a hash (also known as a map), you can use the syntax: mapName[keyName]. Here’s an example:

package main
import "fmt"
func main() {

    // Creating a map

    myMap := map[string]string{"apple": "red", "banana": "yellow", "grape": "purple"}
// Getting the value of a specific key

    fmt.Println(myMap["apple"]) // Output: red

    fmt.Println(myMap["banana"]) // Output: yellow

    fmt.Println(myMap["grape"]) // Output: purple

}

In this example, we created a map with three key-value pairs representing fruits and their colors. We then printed the value of each fruit by calling the map with the corresponding key. The output is the color of each fruit.
