// -- Challenge 2 -------------------------
// Make a boolean function that says whether
// a given person wrote any of the articles.
// Use the names function you wrote above
// with _.compose and _.contains.

var isAuthor = _.identity; // change this
assertEqual(
  false,
  isAuthor('New Guy', articles)
);
assertEqual(
  true,
  isAuthor('Debbie Downer', articles)
);

  var isAuthor = function (name, articles) {
  return _.compose(_.contains(name), names)(articles)
}

Later we will a lot more examples where ​compose​ will be very useful.
