JavaScript Basic: Exercise-47 with Solution

Write a JavaScript program to check whether a given number is presents in the range 40..10000.
For example 40 presents in 40 and 4000.

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 a given number is presents in the range 40..10000. </title>
</head>
<body>

</body>
</html>

JavaScript Code:

function test_digit(x, y, n) 
  {    
    if (n < 40 || n > 10000)
      return false;
    else
      if (n >= x && n <= y)
        return true;
      else
        return false;
  }
console.log(test_digit(40, 4000, 45));  
console.log(test_digit(80, 320, 79));  
console.log(test_digit(89, 4000, 30));

Sample Output:

true
false
false

Flowchart:

ES6 Version:

function test_digit(x, y, n) 
  {    
    if (n < 40 || n > 10000)
      return false;
    else
      if (n >= x && n <= y)
        return true;
      else
        return false;
  }
console.log(test_digit(40, 4000, 45));  
console.log(test_digit(80, 320, 79));  
console.log(test_digit(89, 4000, 30));

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());
