>Regarding your examples: PSET corresponds to `ctx.fillRect(x, y, 1, 1)` on a canvas, reading a pixel corresponds to `ctx.getImageData(x, y, 1, 1)`.

What is a `ctx` and why do I need that? These are all hacks. Graphics programming in bolted on HTML in the form of canvas. It is a horrible platform for doing fun graphics programming when compared to qbasic.

>For delays, you define "sleep" (one line) and write "await sleep(500)" inside a loop, just like with "SLEEP" in QBASIC.

Kindly provide the code for this sleep function and tell me how a beginner who is trying draw some graphics on screen is supposed to figure that.
