JavaScript: Compute the absolute difference between a specified number and 19

JavaScript Basic: Exercise-17 with Solution

Write a JavaScript program to compute the absolute difference between a specified number and 19. Returns triple the absolute difference if the specified number is greater than 19.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JavaScript program to compute the absolute difference between a specified number and 19.  Returns triple their absolute difference if the specified number is greater than 19.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function diff_num(n) {
  if (n <= 19) {
    return (19 - n);
    }
  else
    {
     return (n - 19) * 3;
    }
}

console.log(diff_num(12));
console.log(diff_num(19));
console.log(diff_num(22));

Sample Output:

7
0
9

JavaScript: Tips of the Day

Parse an HTTP Cookie header string and return an object of all cookie name-value pairs

Example:

const parseCookie = str =>
  str
    .split(';')
    .map(v => v.split('='))
    .reduce((acc, v) => {
      acc[decodeURIComponent(v[0].trim())] = decodeURIComponent(v[1].trim());
      return acc;
    }, {});
console.log(parseCookie('foo=bar; equation=E%3Dmc%5E2')); // { foo: 'bar', equation: 'E=mc^2' }

Output:

[object Object] {
  equation: "E=mc^2",
  foo: "bar"
}
