  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check the total marks of a student in various examinations</title>
</head>
<body>

JavaScript Code:

function exam_status(totmarks,is_exam)
  {
  if (is_exam) {
    return totmarks >= 90;
  }

JavaScript: Tips of the Day

How to insert an item into an array at a specific index (JavaScript)?

What you want is the splice function on the native array object.

arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:

var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
