JavaScript: Check whether two given integer values are in the range 50..99

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to check whether two given integer values are in the range 50..99 (inclusive). Return true if either of them are in the said range.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function check_numbers(x, y) 
  {
  if ((x >= 50 && x <= 99) || (y >= 50 && y <= 99))
  {
    return true;
  } 
  else 
  {
    return false;
  }
}

console.log(check_numbers(12, 101));
console.log(check_numbers(52, 80));
console.log(check_numbers(15, 99));

Sample Output:

false
true
true

Flowchart:

ES6 Version:

function check_numbers(x, y) 
  {
  if ((x >= 50 && x <= 99) || (y >= 10 && y <= 99))
  {
    return true;
  } 
  else 
  {
    return false;
  }
}

console.log(check_numbers(12, 101));
console.log(check_numbers(52, 80));
console.log(check_numbers(15, 99));

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());
