wrap canvas context methods

canvas-tracker.js

const canvas = document.getElementById('myCanvas');
const ctx = canvas.getContext('2d');

// Save the original method
const originalFillRect = ctx.fillRect;

// Override it
ctx.fillRect = function(x, y, width, height) {
  console.log("Called fillRect with:", x, y, width, height);
  
  // Call the original method so the canvas still works
  return originalFillRect.call(this, x, y, width, height);
};

// Now when you draw:
ctx.fillRect(10, 10, 100, 50);  // This logs AND draws
