JavaScript FUCTION

[KISHOR 1988]

function monitorCount(rows, columns) {
  return rows * columns;
}

function costOfMonitors() {
  return monitorCount(rows, columns) * 2000

}

monitorCount(5, 7)

console.log(costOfMonitors());

THOUGH I HAVE PASSED ARGUMENT FOR ROWS AND COLUMNS , WHY AM I NOT GETTING VALUE IN CONSOLE?

}

 function costOfMonitors() {
  return monitorCount(rows, columns) * 2000
}

monitorCount(5, 7)

console.log(costOfMonitors());

Though i have passed arguments for rows and columns , why am i not getting data in console??

Because you have not defined rows and columns. Define it and you will get it in console.

I have passed arguments in monitorCount(5, 7) , is this not right?

You have to define it for costOfMonitors(). Because costOfMonitors() does not know anything about raws and columns.

You are passing the arguments in wrong place and calling function somewhere else and what ends up happening is when you are passing the values it works but you are not previewing that and when are previewing it you are not passing the value. I think you are very confused how a function works in JavaScript. Regardless here is the code to make that work:

 function monitorCount(rows, columns) {
        return rows * columns;
      }

      function costOfMonitors(rows, columns) {
        return monitorCount(rows, columns) * 2000;
      }

      console.log(monitorCount(5, 7)); // first fucntion works.

      console.log(costOfMonitors(5, 7)); // to call the first function with second function.

I would recommend reading this blog to get better understanding of the functions in JavaScript.
