Mocking with Jest

Start in index.js. getQuote is a simple function that calla fetchData to get a quote from an API. getQuote then returns the quote as a formatted string.

There's a simple test for it in index.test.js. Run it with npm test to confirm it passes.

We want to test getQuote without it making a real call to the API each time. We can use Jest's mocking feature to mock the fetchData function.
