</html>

JavaScript Code:

function max_even(arra) {

  arra.sort((x, y) => y - x);

  for (var i = 0; i < arra.length; i++) {
    if (arra[i] % 2 == 0)
      return arra[i];
    }
  }

console.log(max_even([20, 40, 200]));
console.log(max_even([20, 40, 200, 301]));

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
