JavaScript Basic: Exercise-74 with Solution

Write a JavaScript program to find the larger value between the first or last and set all the other elements with that value. Display the new array.

Pictorial Presentation:

JavaScript: Find the larger value between the first or last and set all the other elements with that value.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to find the larger value between the first or last and set all the other elements with that value.  Display the new array.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function all_max(nums) 
 {
    var max_val = nums[0] > nums[2] ? nums[0] : nums[2];

    nums[0] = max_val;
    nums[1] = max_val;
    nums[2] = max_val;

    return nums;
}
console.log(all_max([20, 30, 40]));
console.log(all_max([-7, -9, 0]));
console.log(all_max([12, 10, 3]));

Sample Output:

[40,40,40]
[0,0,0]
[12,12,12]

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
