 * Challenge: hook up our form so it (halfway) works.
 * 
 * 1. Pull in the `loginUser` function from the api.js file
 * 2. Call loginUser when the form is submitted and console.log 
 *    the data that comes back. Use "b@b.com" as the username and
 *    "p123" as the password.
 * 
 *    NOTE: loginUser returns a promise, so you'll need
 *    a .then(data => {...}) to access the data, or use
 *    a separate aync function defined inside handleSubmit
 * 3. TBA
