Hello experts,<br />
<br />
I want to take an array containing numbers, find the highest number within and change it to 100 (which represents 100%).<br />
<br />
I then want to change all the remaining numbers to a percentage of the original highest number.<br />
<br />
So for example if I had the following array:<br />
<br />
var store = new Array(18, 200, 124, 98)<br />
<br />
...I want it to end up like this...<br />
<br />
(9, 100, 64, 49)<br />
<br />
200 becomes 100 as it is the largest number in the array, 18 becomes 9 as it's 9% of 200, 124 becomes 64 as it's 64% of 200, etc...<br />
<br />
Thanks in advance!<br />

Convert values in an array to percentage

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
