Sum all values in an object

Can someone help me to pass this? This is only returning the first value. And when I try to use += it shows an error.

function addValues(obj) {
for (let key in obj) {
let sum = obj[key];
return sum;
}
}

Type your question above this line.

Hello @Lepros

Following is the correct code:

function addValues(obj) {
    let sum = 0;
    for (let key in obj) {
        sum = sum + obj[key];
    }
    return sum;
}

Issue in your implementation is that you are just returning the number in first key of the object. You are essentially not summing up the numbers.

Hope this helps!

Thank you for all your help. I noticed I had some of the same mistakes as my other post’s problem. I need to remember to declare the variable and return it outside of the loop. Thank you!
