How to get length of a map in golang?
October 26, 2022Hi Friends 👋,
Welcome To aGuideHub! ❤️
To get length of a map, use len(myMap) method it will count and return numbers of element of map.
In golang the len() method used for counts element of map.
Let’s start
package main
import "fmt"
func main() {
mymap := make(map[string]string)
mymap["first"] = "aguidehub"
mymap["second"] = "infinitbility"
mymap["third"] = "sortoutcode"
fmt.Println("Length of map", len(mymap))
}In the above program, we are accessing length of map, let’s see the output.
Output:
Length of map 3All the best 👍
