You're requiring in your file reader here in the index, but you're not using it here.
Write a version of the function call for the readFiles method so that you can call it here in the index file, and not just in the test file.

Basically, I want you to create a function much like how you did in your tests to take the data from your three files and print them out or do something with them in a meaningful way.

Nice use of returning the callback of the error.

Nice work making the input an array of paths.

| result.push(data.toString('hex', 0,8)); | ||

Great work calling the callback at the bottom with the resulting information and a null for the first argument. Perfect ansynchronous callback pattern.

Good stuff with the double bang here.

Nice work using the before block like Brian did during class.

Perfect way to check the call is being made asynchronously.

Great use of done here to end things.

my tests work and then they dont work when i try to fix things.
