To check value exists in a golang map, use if...else statement with loop of map if any iteration value match with your value it’s means map contains your value.
Today, I’m going show you how do i check value exists in golang map.
Let’s start
Check value exists in golang map
Here, we will create s sample map with some data and try to check value contain in map.
package main
func isValueExists(userValue string, mymap map[string]string)bool{
for _, value:= range mymap{
if(value == userValue){
return true
}
}
return false
}
func main() {
mymap := make(map[string]string)
mymap["first"] = "aguidehub"
mymap["second"] = "infinitbility"
mymap["third"] = "sortoutcode"
userValue := "aguidehub"
if isValueExists(userValue,mymap){
println("Value Exists")
}else{
println("Value NOT Exists")
}
}In the above program, we are trying to check value in map, let’s see the output.
Output:
Value ExistsAll the best 👍
