offscreen canvas and web worker

Question

Hello all. So I have been playing around with canvas lately and was wondering if anyone knew how to render to canvas from offscreen canvas properly. this is pretty much where im at:

let canvas = document.querySelector("canvas").transferControlToOffscreen();
let worker = new Wokrker("canvasworker.js");

worker.postMessage({canvas:canvas},[canvas]);

in worker i set canvas to canvas and ctx to context 2d...

What will this do out of curiosity?
