New Quote button not working Tweet out button undefined

Hi I am working on my quote generator machine, I implemented API to my project. The problem is my New Quote button won’t display quotes and my tweet out button is undefined. Please help I been trying to wrap my head around this for almost an hour and couldn’t come up with anything.

Use https for the quote API URL.

Set the randomQuote variable’s value inside the getJSON callback after displaying the quotes on the page.
