Question about Variables - JavaScript

Hi guys, I'm stuck!

A variable named "boxWidth" already exists with a value of "640px". Create a new variable named "numWidth" and use the "parseInt" method to extract the numeric value from boxWidth's string value.

Here's my answer:

var numWidth = parseInt("boxWidth", 10);

What am i doing wrong?

Thanks!!

This is not working because you have placed the variable name within quotations. This means you are passing parseInt a string instead of your variable.

Try this code:

var numWidth = parseInt(boxWidth, 10);

You should remove the quotes around boxWidth so you're referring to the variable boxWidth rather than the string "boxWidth."

The variable boxWidth has a string value of "640px," which will be converted by parseInt to an integer. Hope this helps! Please feel free to ask any further questions you need to.

[Erik's excellent response wasn't there when I started writing mine. I'd delete mine if I could, since I'm saying the same thing he is.]
