This one is actually correct: https://codepen.io/becky-intelletive/pen/wvzNxOr (I added some html to illustrate the result) In summary: the change() function gets references to the sampleStudent and sampleCourse. For the student, it updates the reference, thus preserving the original in its original state ("HTML student"). For the course, we aren't updating the reference. We're using the reference to access the object's keys. Since they are the "real" keys and not references to the keys, we are therefore updating their "real" values. The original values thus get overwritten.

The correct answer is: HTML Student, JavaScript, 100. Why? Because you are only updating the 'course' name, not the property values. To update the proerty values you would have to call them: console.log(sampleStudent, sampleCourse.name = "html", sampleCourse.grade = "90");

The only correct answer in this solution is the grade. Student = 'JavaScript Student' & Course = 'JavaScript'. I'm beginning to believe each one of these solutions is incorrect.
