JavaScript JavaScript Basics (Retired) Working With Numbers Numbers and Strings

Let's assume we have 10 <div> tags on a page. Each is 190 pixels wide. Using the two variables in this script, create a new variable named totalWidth that multiples the width by the numOfDivs variable. You'll need to use a JavaScript function to retrieve the number value from the string in the width variable.

app.js 
vvar width = '190px'; 
var numOfDivs = 10; 
var totalWidth = parseInt(width) * parseInt(numOfDivs);
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>

You don't need to parseInt on numOfDivs (it is a number, not string)

var totalWidth = parseInt(width) * numOfDivs;

This code let me pass the challenge.
