Nested Maps in Golang

nested_maps.go

package main

import "fmt"

func main() {
	// shoppingList is a map that has a map inside it
	shoppingList := make(map[string]map[string]int)

	// veggies key points to veggiesMap
	veggiesMap := map[string]int{"onion": 2, "orka": 3}
	shoppingList["veggies"] = veggiesMap

	// fruits key points to fruitsMap
	fruitsMap := map[string]int{"banana": 12, "apples": 5, "oranges": 3}
	shoppingList["fruits"] = fruitsMap

	// Returns Shopping list categories:

	// Category: veggies
	// Category Details: map[onion:2 orka:3]

	// Category: fruits
	// Category Details: map[banana:12 apples:5 oranges:3]
	fmt.Println("Shopping list categories:")
	for key := range shoppingList {
		fmt.Println("Category:", key)
		fmt.Println("Category Details:", shoppingList[key])
	}

}

It's a great demo! Thanks your code.
