HTML Code:

<!DOCTYPE html>
<html>
<head>

  <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));

JavaScript: Tips of the Day

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)

Example:

const isAnagram = (str1, str2) => {
  const normalize = str =>
    str
      .toLowerCase()
      .replace(/[^a-z0-9]/gi, '')
      .split('')
      .sort()
      .join('');
  return normalize(str1) === normalize(str2);
};
console.log(isAnagram('iceman', 'cinema')); // true

Output:

true
