need help with trailhead: Visualforce Basics

Hello. This is a really newbie question but I haven't done coding in a while and got stuck. The Visualforce Basics trailhead says to Open your browser’s JavaScript console and enter the following code for format your Visualforce page with Lightning.

$A.get("e.force:navigateToURL").setParams(
    {"url": "/apex/pageName"}).fire();

I know how to get to the Chrome DevTools, but how do you run Javascript inside it?

Hi Denise,

This part is badly explained and it is the only time that I had done this with the trailhead modules and because I had taken javascript classes before, I could do:  https://developer.salesforce.com/forums/ForumsMain?id=9060G000000BiGt

Best regards

To access the DevTools, on any web page or app in Google Chrome you can use one of these options: Open the Chrome menu at the top-right of your browser window, then select Tools > Developer Tools. Right-click on any page element and select Inspect Element.

Or Press F12, Ctrl + Shift + I

Thanks Raj,
I can't get it to work. I'm getting 
Uncaught ReferenceError: $A is not defined
    at <anonymous>:1:1

You are supposed to go back to Lightning Experience before executing the JavaScript snippet, and the Trailhead doesn't exactly make that clear.

Check out this similar thread: Getting '$A is not defined' error while doing VF Trailhead (https://developer.salesforce.com/forums/?id=9060G0000005MvtQAE)
