My test script does not pass, throws an error

My test script throws an error even thou it same as the instructor's own.

var expect = require("chai").expect;

function titleCase(title) {
  var words = title.split("");
  var titleCasedWords = words.map(function(word) {
    return word[0].toUpperCase() + word.substring(1);
  });

  return titleCasedWords.join("");
}

expect(titleCase("the great mouse detective")).to.be.a("string");
expect(titleCase("a")).to.equal("A");
expect(titleCase("vertigo")).to.equal("Vertigo");
expect(titleCase("the great mouse detective")).to.equal(
  "The great Mouse Detective"
);

1) There is a space between the empty double quotes - here:

var words = title.split(" ");

and here:

return titleCasedWords.join(" ");

2) The G in the 2nd Great should be uppercase here:

expect(titleCase("the great mouse detective")).to.equal("The Great Mouse Detective")
