Making a minimalistic random quote machine

I’ve made this and it should work, but it doesn’t! I checked everything and still have no idea why. Any suggestions?

Whenever you troubleshoot, always look at your browsers console first.
One look and you see this error:

Uncaught ReferenceError: getQuote is not defined

Make sure, function calls match exactly with the function’s name.

You also have another incidental error:

bootstrap.min.js:6 Uncaught Error: Bootstrap’s JavaScript requires jQuery. jQuery must be included before Bootstrap’s JavaScript.

Which tells you exactly what you need to do to fix it
