Introduction to Variables
This video introduction to variables provided by Khan Academy features a live code editor alongside the display of the code. Notice how the changes to the code on the left change the display of the image on the right. When programming on Khan Academy, that is a fun and unique feature which you get to have as you write code for projects or for fun on their site. The display is a little cut off on our site so for a slightly better viewing experience you can click the title of the video or the "View on Khan Academy" button - they both are links to the video on Khan Academy's website.
Another thing you can do is assign variables equal to other variables.
