CS 105 Introduction to Computer Programming using JavaScript 
 
Lab 1:  
I Love to Draw 
 
Watch the Khan Academy videos linked for Week 1 on the class website. 
Use JavaScript and HTML5 canvas to draw (using lines, rectangles, and arcs) a few pictoglyphs 
that together convey some message. You may use cultural pictoglyphs or those of your own 
invention. The message should be very simple. The idea is to have between 10 and 25 draw 
commands – not pages of code, but not a blank canvas with the message of a polar bear lost in 
a blizzard. 
After you get the drawing the way you want it on the Khan Academy website, download, from 
the class website: CS105_Lab1_MyFirstName_MyLastName.html 
Change the file name to use your actual first and last name (NO BLANKS). 
Within the file, change the title to your name followed by "CS 105 Lab 1: I Love to Draw." 
Replace the face drawing code with your code copy and pasted from the Khan Academy 
website. 
Attach the .html file in Blackboard Learn under Lab 1. 
Note: If you get the following error when you attempt to attach your .html file in Blackboard: 
 
Then place your file in a .zip archive and attach the .zip archive. See lecture notes for how to do 
this.
