Think of it as your DOM. Hack #1: The requestAnimationFrame Override Most animations rely on requestAnimationFrame (rAF). The hack? Throttling or batching rAF calls to reduce CPU/GPU load without perceptible loss.
By artificially limiting frames, you free up the main thread for JavaScript execution, making interactions feel snappier.

Move all canvas rendering to a Web Worker using OffscreenCanvas . html5 speed hack

// Your heavy rendering here updateDOM(); requestAnimationFrame(speedHackAnimation); } Throttling or batching rAF calls to reduce CPU/GPU
// Main thread const canvas = document.getElementById('gameCanvas'); const offscreen = canvas.transferControlToOffscreen(); const worker = new Worker('canvasWorker.js'); worker.postMessage({ canvas: offscreen }, [offscreen]);
