In this project are we mining the internet for quotes automatically or are we harcoding the quotes into the codepen?
You are pulling quotes from an API.
But some just harcode them 
Sometimes it helps to break projects up into a series of discrete steps.
When I did my quote machine, I hardcoded a couple of quotes, just so I would have something to test while I filled in the rest of the code.
Replacing these hardcoded quotes with an actual API became the final step.
