i was certain this was correct

not sure why my syntax is wrong.

script.js 
var objects = [
   var object_a = {object1: thing1, object2: things2}, 
   var object_b = {object3: things3, object4: things4}, 
   var object_c = {object3: thing5, object2: things5}
]
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Objects</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

It should look like this:

var object_a = {object1: thing1, object2: things2};
var object_b = {object3: things3, object4: things4};
var object_c = {object3: thing5, object2: things5};

var objects = [
   object_a,
   object_b,
   object_c
];

The problem is the following syntax: 

var object_a = {object1: thing1, object2: things2};

Is what we call a variable declaration, you can't use a variable declaration as a (non-parameter) value. That is what is the syntax error you are running into. Instead, you must pass in the value of the declaration.

probably because the variables thing1, thing2, thing3, thing4, thing5 don't exist. I was just correcting your syntax, I assumed that you had already created and assigned values to those variables. Otherwise, it should look like this:

var thing1 = 1, things2 = 2, things3 = 3, things4 = 4, things5 = 5;
var object_a = {object1: thing1, object2: things2};
var object_b = {object3: things3, object4: things4};
var object_c = {object3: thing5, object2: things5};

var objects = [
   object_a,
   object_b,
   object_c
];

or more concisely like so:

var objects = [
   {object1: 1, object2: 2},
   {object3: 3, object4: 4},
   {object3: 5, object2: 5}
];

yeah they wanted me to just put the objects inside the array without defining them outside of it. the second example worked. thank you!
