file.js

/*
 
In this challenge you will be creating a series of variables.
The values of the variables will be different types of JavaScript
objects.
 
Below you will find driver code. Run the code in this file either
from the command line using Node.js or by pasting the code of this
entire file into your browser console.  All tests will log 'true'
in the console when they pass--false, otherwise.
 
The tests will tell you what to do next.  Run the code and read the
message explaining why the code couldn't be run or why the test failed.  The
first step is going be to make the first test pass.  Then make the second
test pass, and so on.
 
Hint:
If you get an error message that says something like ...
 
"ReferenceError: secretNumber is not defined" ...
 
try declaring a variable with that name (e.g., secretNumber).
