JavaScript: Find the maximum difference between any two adjacent elements of a given array of integers

JavaScript Basic: Exercise-92 with Solution

Write a JavaScript program to find the maximum difference between any two adjacent elements of a given array of integers.

Pictorial Presentation:

JavaScript: Find the maximum difference between any two adjacent elements of a given array of integers.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Find the maximum difference between any two adjacent elements of a given array of integers.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function max_difference(arr) {
	var max = -1;
    var temp;
	for (var i = 0; i < arr.length - 1; i++)
      {
		temp = Math.abs(arr[i] - arr[i + 1]);
		max = Math.max(max, temp);
	  }
	return max;
}

console.log(max_difference([1, 2, 3, 8, 9]))
console.log(max_difference([1, 2, 3, 18, 9]))
console.log(max_difference([13, 2, 3, 8, 9]))

Sample Output:

5
15
11

      {
		temp = Math.abs(arr[i] - arr[i + 1]);
		max = Math.max(max, temp);
	  }
	return max;
}

console.log(max_difference([1, 2, 3, 8, 9]))
console.log(max_difference([1, 2, 3, 18, 9]))
console.log(max_difference([13, 2, 3, 8, 9]))

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
