Hello, my task was to make two constructors for the code that I also posted and they are not working. Can somebody help me figure out why they are not working. I posted them right below.

here are my constructors for course and Faculty

course.js:

function Course (name, times, instructorName, instructorDept ) {
this.name = name ||"unknown course name";
this.times = times||"unknown time";
this.instructor = new Faculty(instructorName, instructorDept);


this.getname = function();
this.setname = function( name );

this.gettimes = function();
this.settimes = function( dept );

this.getinstructor() = function();
this.setinstructor(Faculty);

this.name.toString = function();
}

faculty.js:
function Faculty(name, dept) {
this.name = name || "unknown";
this.dept = dept || "unknown";

this.getname = function();
this.setname = function( name );

this.getdata = function();
this.setdata = function( dept );

this.name.toString = function();
this.dept.toString = function();
}

Here is the test file testprob1.js:

var fac1 = new Faculty( "Dr. Smith", "Math" );

document.writeln( "New faculty: " + fac1.getname() + ", " + fac1.getdept() + "<br>" );

document.writeln( "Again: " + fac1 + "<br><br>" );

var fac2 = new Faculty();

document.writeln( "New faculty: " + fac2.getname() +

", " + fac2.getdept() + "<br>" );

fac2.setname( "Dr. Jones" );

fac2.setdept( "CS" );

document.writeln( "Updated: " + fac2.getname() +

" " + fac2.getdept() + "<br><br>" );

var crs1 = new Course( "COMP322", "MWF 1:00-1:50",

"Dr. Green", "CS" );

document.writeln( "New course: " + crs1.getname() +

", " + crs1.gettimes() +

", " + crs1.getinstructor() + "<br>" );

document.writeln( "Again: " + crs1 + "<br><br>" );

var crs2 = new Course();

document.writeln( "New course: " + crs2.getname() +

", " + crs2.gettimes() +

", " + crs2.getinstructor() + "<br><br>" );

crs2.setname( "COMP590" );

crs2.settimes( "TR 1:00-2:15" );

crs2.setinstructor( fac2 );

document.writeln( "Updated: " + crs2.getname() +

", " + crs2.gettimes() +

", " + crs2.getinstructor() );

I've shortened out your code and skipped some of the unecessary lines inside the two constructors.

You'll need to run this entire document, to see the actual effects of the two functions.

Here's the code:

   /* Commented Block Started

   this.getname = function( name ) { }; // Creating Empty function. And also you forgot to include brackets, so that's why it's messing the whole program.

   this.setdata = function( dept ) { };
   this.name.toString = function() { };

Thanks a lot. Even though the bottom part doesn't show up, I can try to figure it out with the stuff you gave me all ready.
