Golang : Array mapping with Interface
New comers to Golang often have slight difficulty understanding how interface works in Golang. This is a simple tutorial to demonstrate how to map arrays with interface.
package main
import (
"fmt"
)
var strArray = []string{"abc", "def", "ghi"}
var strMap = map[string]interface{}{}
var intArray = []int{1, 2, 3}
var intMap = map[int]string{}
func main() {
for i := 0; i != 3; i++ {
fmt.Println(intArray[i], "\t", strArray[i])
intMap[i] = strArray[i]
strMap[strArray[i]] = intMap
}
fmt.Println("String map : ", strMap)
fmt.Println("Integer map : ", intMap)
}
Output :
1 abc
2 def
3 ghi
String map : map[ghi:map[0:abc 1:def 2:ghi] abc:map[0:abc 1:def 2:ghi] def:map[0:abc 1:def 2:ghi]]
Integer map : map[0:abc 1:def 2:ghi]
