How to add a variable's value to an array function?

Question

I'm trying to add the random number to the array which is assigned to a function that keeps adding the numbers together.

function getMiNumber(number){
    var value = Math.floor(Math.random() * 10) + 1 ;
    value.push(value.value);

    var myArray = someCalc([0]);
    console.log(myArray);
    function showMe(val) {
      var presentMe = document.getElementById('someId');
      presentMe.innerHTML = val;
    }
    showMe(myArray);

            function someCalc(list) {
      var total = 0;
      for(var i = 0; i < list.length; i++){
        total += list[i];
      }
      return total;
    }

}

well ... the argument number is never used in the function, value.value is undefined, as a Number does not have a property called value, and value doesn't have .push method, as it is not an Array ... that's just lines 1, 2 and 3 of your code - line 3 would produce an error in developer tools console ... — Jaromanda X

and line 5 will always result in the myArray being the value 0 — Jaromanda X

UPDATE

Reread the question and determined that a cumulative total is desired so this demo will:

Generate a random number 1 to 10.
- Display that number.
Add that number to an array.
- Display that array.
Add all of the array's elements.
- Display that total.

The array is pre-determined in this demo var xArray = [23, 8, 90, 7];

function randomNumber(xArray){
    var value = Math.floor(Math.random() * 10) + 1 ;
    xArray.push(value);
		return xArray;
}
    var xArray = [23, 8, 90, 7];
    var total = calc(randomNumber(xArray));
    console.log(total);
    function output(total) {
      var out1 = document.getElementById('out1');
      out1.value = total;
    }
    

 function calc(list) {
      var total = 0;
      for(var i = 0; i < list.length; i++){
        total += list[i];
      }
      return total;
    }

output(total);

<output id="out1"></output>
