Remember that in step 1 you selected the Load More Authors button and assigned it to loadMoreBtn.

Use addEventListener to add a "click" event listener to loadMoreBtn. Also, pass in a reference to the fetchMoreAuthors function to run whenever the button is clicked.

After that, when you click the button you should see 8 more authors.

--before-all--

window.fetch = () => Promise.resolve({json: () => Promise.resolve([{ author: 'Whoever', image: 'data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==', url: "http://not-a-real-url.nowhere/", bio: 'words go here' }])});

--hints--

You should call the addEventListener() method on your loadMoreBtn variable.

assert.match(code, /loadMoreBtn\.addEventListener\(/)

Your event listener should listen for a "click" event.

assert.match(code, /loadMoreBtn\.addEventListener\(\s*('|"|`)click\1/)

Your event listener should take fetchMoreAuthors as the function to run.

assert.match(code, /loadMoreBtn\.addEventListener\(\s*('|"|`)click\1\s*,\s*fetchMoreAuthors\s*\)\s*;?/)
