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

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]

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

    return nums;
}
console.log(all_max([20, 30, 40]));

JavaScript: Tips of the Day

Classes/function constructors

class Person {
  constructor() {
    this.name = 'Owen';
  }
}

Person = class AnotherPerson {
  constructor() {
    this.name = 'Eddie';
  }
};

const member = new Person();
console.log(member.name);

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Eddie, so the name property on the new Person instance member is "Eddie".
