JavaScript Code:

function max_of_three(x, y, z) 
 {
  max_val = 0;
  if (x > y)
  {
    max_val = x;
  } else
  {
    max_val = y;
  }
  if (z > max_val) 
  {
    max_val = z;
  }
  return max_val;
}

console.log(max_of_three(1,0,1));
console.log(max_of_three(0,-10,-20));
console.log(max_of_three(1000,510,440));

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
