Javascript regex on array

I currently have this example array:

array = [1.2%, 16%, 9.0%, 8%]

I want to get the highest number so I did this:

Math.max.apply(null, array);

But it shows an error maybe because of the ‘%’

How can I filter the array using regex? It’s my first time using regex on the array. I already spent more than 2 hours I still don’t get it.

Here are my works that did not work:

array = [1.2%, 16%, 9.0%, 8%].match(/[0-9]*\.?[0-9]/);
array = [1.2%, 16%, 9.0%, 8%].replace(/[0-9]*\.?[0-9]/);
array = [1.2%, 16%, 9.0%, 8%].match(/[\d]+/);

Sorry I am new to javascript. Thanks.

>Solution :

You can map the strings to parseFloat, then the "%" will be ignored:

let array = ["1.2%", "16%", "9.0%", "8%"];

let result = Math.max(...array.map(parseFloat));

console.log(result);

NB: I used the spread syntax here instead of apply, just because that is the more modern way to write it (since EcmaScript 2015).
