While adding two numbers getting NAN as output in the react?

Question

When I am trying to add two numbers, I am able to get NaN. If anyone has any advice, any help would be greatly appreciated.

This is my Code:-

  var sum = parseInt(label.labellength, 10) + parseInt(label.labely, 10);
  console.log("Sum of FrontRight is " + sum );

Output is:-NaN

I tried as following :

Using Number

  var sum=Number(label.labellength) + Number(label.labely);

Output is:-NaN

Check the values of label.labellength and label.labely. They both might not be numbers. — tomerpacific, Jul 19 '22 at 09:46
Can you add the following statement print content of these variables? `console.log(label.labellength, parseInt(label.labely)` — The KNVB, Jul 19 '22 at 09:51

The same issue came to me , try to use || operator and return it, it did the same and it worked for me...

const [contextOverHr,setContextOverHr=useState("")
return (
  {Object.values(workHour).reduce((pre,total) => {
                  let totalNum = pre + total.OverHour
                  setContextOverHr (totalNum)
                  return totalNum || 0
                },0)
  }
)
