How to sonvert a string in int

app.js 
var width = '190px';
var numOfDivs = 10;

//Imagine you have 10 <div> tags on a web page. Each div is 190 pixels wide. Using the two variables in this script, create a new variable named totalWidth that multiplies the width by the numOfDivs variable. 
//Because the width variable is a string, you'll need to use a JavaScript function to retrieve the number value.
var totalWidth = numOfDivs * parseInt(width);
