my first spin off in Khan academy

Spin-off of "Project: What's for Dinner?" Pizza

Made using: Khan Academy Computer Science.

Khan academy

I will explore the Khan academy JS course and compare it to codeacademy

so I really like Khan academy, you are actually taught by other people and there is much more collaboration also you get to have more variety in what you can do

5/5

I am going to work on codeacademy Javascript lesson Arrays and Objects in JS

5/1

finally found a way to incorporate && and || into my Javascript Choose Your Own Adventure 2. While Codeacademy said it worked, there is at least one logical error in my code. I put the code on the server and the problem still exists. Here is the source code.
