You're adding quotes around window object which return null value back that's why code is not working as expected.

Hi there, In future reference you can place all of your code within 3 backticks ` on both sides of your code. Also, after the first 3 backticks you can place the language, (html, javascript, css etc.) this allows it to color code the language appropriately. For other references when composing questions/responses, please see the "Markdown Cheatsheet" below your textbox.

var example = "Example JavaScript Code";
