JS Canvas shape duplication issues
He guys, I just bumped into this issue while creating a drawing app. I started with stroke rectangle shapes, it works fine in some places inside the canvas but when it reached around 50% to the right of the canvas it keeps printing. I really appreciate if someone can help point what is wrong with this code thank you!

i think it would be easier to have a temporary canvas (on top of the standard one) where you live draw the rectangle (clear the canvas every tick). only when the mouse is released, you draw the rectangle (start / end pos) to the standard one. that way you don't need to consider/redraw previous added shapes
I see this makes more sense, thank you!
