What am I doing wrong here? JS Challenge

I'm not sure what I am doing wrong here. I obviously am not sure as to what is being asked. Please help.

script.js 
var objects = [

  var student = {
      firstName: "daniel",
      lastName: "flynn",
      middle: "j";

}

  var grades = {
      homeWork: [93],
      tests: [97],
      quizScores: [98]; 

}

  var address = {
      city: "Sheridan",
      county: "Yanhill",
      street: "Bridge";
}

];

var students = [ 
{
      firstName : "daniel",
      lastName : "flynn",
      grade : "A"
},
{
      firstName : "John",
      lastName : "Doe",
      grade : "B"
},
{
      firstName : "Sam",
      lastName : "Smith",
      grade : "C"
}
];

The idea is to have an array of student objects, each is a different student but each has the same information about each student: their first name, last name and grade, for example. They shouldn't be variables. You also need commas between the different array objects.

You seem to understand the gist of the task, but there are some fundamental issues with your code:

  1. Arrays cannot store variable declarations. Arrays are just a list of values separated by a comma.
  2. Putting a semicolon after the last property of an object is invalid. No special symbol is needed after the last property.
  3. The challenge asks for each object to have two properties, you have given them three.

If you remove all of the variable declarations, remove the semicolons and remove the third property of each object. Like this:

var objects = [
  {
      firstName: "daniel",
      lastName: "flynn"
  },
  {
      homeWork: [93],
      tests: [97]
  },
  {
      city: "Sheridan",
      county: "Yanhill"
  }
];

Then your code will pass the challenge.
