Syntax Error on Drawing Script (JavaScript)
<p>I'm writing a program for my class (javascript) that simply draws lines on a canvas. And uses the alt key to draw white and give the appearance of it being 'Erased'. I finished the code, but i'm getting a syntax error and can't see what i'm doing wrong. Can you guys please help?</p>
