Simple Js function giving me undefined as output

April 28, 2022

I am trying to solve this simple js function question but its giving the undefined as output along with the correct answer. I know its probably because of the return value issue but how solve in this situation?

function findMax(a,b,c){
    if(a>b && a>c){
        console.log("a" + " is max")
    }else if(a<b && b>c){
        console.log("b" + " is max")
    }else{
        console.log("c" + " is max")
    }
}
console.log(findMax(2,4,5))

>Solution :

your console logging the return value which is undefined. just get rid of the last con sole log.

function findMax(a,b,c){
    if(a>b && a>c){
        console.log("a" + " is max")
    }else if(a<b && b>c){
        console.log("b" + " is max")
    }else{
        console.log("c" + " is max")
    }
}
findMax(2,4,5);

Or you could return the string


function findMax(a,b,c){
    if(a>b && a>c){
        return "a" + " is max";
    }else if(a<b && b>c){
        return "b" + " is max";
    }else{
        return "c" + " is max";
    }
}
console.log(findMax(2,4,5))
