Can anyone explain me how this possible in javascript?

Question

let sum = 0;
function innerAdd(a,b){
    sum = a + b;
    console.log(sum);
}

innerAdd(5,5,25,25) // Still getting 10 as output

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community, Mar 30 '22 at 17:47
Why would you expect to get something other than 10 when you are adding 5 and 5? — Quentin, Mar 30 '22 at 17:48

Javascript only recognizes the first two values. if you want to be able to add more values you will have to add a for() cycle. something like this:

function sum() {
  var total = 0;
  for (var i = 0; i < arguments.length; i++) {
    total += arguments[i];
  }

  alert(total);
}

sum(1,2,3,4);

this way you can add any number of parameters, sum(5,5,25,25) will be 60.
