JavaScript: Find the maximum difference among all possible pairs of a given array of integers
JavaScript Basic: Exercise-93 with Solution
Write a JavaScript program to find the maximum difference among all possible pairs of a given array of integers.
Sample Solution:
HTML Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Find the maximum difference among all possible pairs of a given array of integers.</title>
</head>
<body>
</body>
</html>
JavaScript Code:
function array_max_diff(arr) {
var max_result = 0;
for(var i=0;i<arr.length;i++)
{
for(var k=0; k!=i && k<arr.length; k++)
{
var diff = Math.abs(arr[i]-arr[k]);
max_result = Math.max(max_result, diff);
}
}
return max_result;
}
console.log(array_max_diff([1, 2, 3, 8, 9]))
console.log(array_max_diff([1, 2, 3, 18, 9]))
console.log(array_max_diff([13, 2, 3, 8, 9]))
Sample Output:
8 17 11
Flowchart:

ES6 Version:
function array_max_diff(arr) {
let max_result = 0;
for(let i=0;i<arr.length;i++)
{
for(let k=0; k!=i && k<arr.length; k++)
{
const diff = Math.abs(arr[i]-arr[k]);
max_result = Math.max(max_result, diff);
}
}
return max_result;
}
console.log(array_max_diff([1, 2, 3, 8, 9]))
console.log(array_max_diff([1, 2, 3, 18, 9]))
console.log(array_max_diff([13, 2, 3, 8, 9]))

JavaScript: Tips of the Day
Randomizes the order of the values of an array, returning a new array
Example:
const tips_shuffle = ([...arr]) => { let x = arr.length; while (x) { const i = Math.floor(Math.random() * x--); [arr[x], arr[i]] = [arr[i], arr[x]]; } return arr; }; const foo = [2, 4, 6]; console.log(tips_shuffle(foo));
Output:
[4, 2, 6]
