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
Flowchart:

ES6 Version:
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));

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" }
