The screen variable and jshint warnings

[queequeg]

I would like to make this warning go away , hopefully by fixing some problem I have:

rl.js|19| jshint warning: Redefinition of 'screen'. 

Here is the tutorial I'm working on:

Here is a gist of code I'm working on from the tutorial.

So my question is what is wrong?  Why am I getting the above warning and how can I avoid having my linter complain?

The warning explains the issue pretty well, you are redefining screen. All of your variables are created globally on the window object. The window object already has a variable named screen and you are initializing a variable named screen on the window object, thus "Redefinition of 'screen'".

To remove the warning change the variable name to an unused name or move it out of global scope.
