Hi, I am doing the classic example of a calculator but I have problems processing a function within the function of the equal button (=). Any suggestions?

var nunArray = [];
var newArray = [];
var operation = false;
var suma = false;
function arrayANumber(array){
var num = "";
for(var i = 0; i < array.length; i++){
    num += array[i];
}
return (parseInt(num));
}
//Accion sumar
 $('#equalsButton').click(function(){
if(suma == true){
    var result = 0;
    result = arrayANumber(numArray) + arrayANumber(newArray);
    var total = result;
    $('#display').val(result);
}else{
    $('#display').val("");
}
});

$('#addButton').click(function(){
operation = true;   
suma = true;
 $('#display').val(nunArray.join(""));

}); 
 $('#button1').click(function(){
  //probar la variable global newArray
    if (operation == true) {
        newArray.push($('#button1').val());
        $('#display').val(newArray.join(""));
    }else{
        nunArray.push($('#button1').val());
        $('#display').val(nunArray.join(""));
    }
});

Get Date and time to send to a struct type variable in c ++ Simple question of! NOT because it does not return what I think

You get an error because you define the variable as nunArray and you send it as numArray

for that reason you leave indefined

var nunArray = [];
var newArray = [];
var operation = false;
var suma = false;

function arrayANumber(array) {
  var num = "";
  for (var i = 0; i < array.length; i++) {
    num += array[i];
  }
  return (parseInt(num));
}
//Accion sumar
$('#equalsButton').click(function() {
  if (suma == true) {
    var result = 0;
    result = arrayANumber(nunArray) + arrayANumber(newArray);
    var total = result;
    $('#display').val(result);
  } else {
    $('#display').val("");
  }
});

$('#addButton').click(function() {
  operation = true;
  suma = true;
  $('#display').val(nunArray.join(""));

});
$('#button1').click(function() {
  //probar la variable global newArray
  if (operation == true) {
    newArray.push($('#button1').val());
    $('#display').val(newArray.join(""));
  } else {
    nunArray.push($('#button1').val());
    $('#display').val(nunArray.join(""));
  }
});
