Clarification for Nested Objects Slides?

[cliffordfajardo]

Hi Bianca, I was reviewing one of your slides & testing it in the chrome console and was receiving a type error message for the following code on your slide.

Slide: http://slides.com/biancagandolfo/obj-arr-func#/4/27

Code that was giving me "TypeError: Cannot set property 'full' of undefined"

var box = {};       
box['innerBox'] = {};                   
box['innerBox'].full = true;
box['innerBox']['height'] = 10;         

box['innerBox2'].full = false;

Here is the code with an extra line (penultimate line) & no error.

var box = {};       
box['innerBox'] = {};                   
box['innerBox'].full = true;
box['innerBox']['height'] = 10;         

box['innerBox2'] = {};
box['innerBox2'].full = false;
