What can't be done without canvas?

Answer 1

This is NOT a philosophical question.
Philosophy is a picture of the world, a worldview, metaphysics, the meaning of life ...
There are three ways to draw on a canvas:
1) you can draw shapes, text and pictures on it
60 times per second, an image is drawn, erased and drawn again
2) you can insert an array of values pixels, also for example 60 times per second, the refresh rate can be any
3) via WebGl
