How can we reproduce the crash?

  }
}

index.js

import { setInterval } from 'bun:timers';
import robot from 'robotjs';

let previousMousePosition = robot.getMousePos();
let totalDistance = 0;

function calculateDistance(x1, y1, x2, y2) {
  return Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2));
}

setInterval(() => {
  const currentMousePosition = robot.getMousePos();
  const distance = calculateDistance(
    previousMousePosition.x,
    previousMousePosition.y,
    currentMousePosition.x,
    currentMousePosition.y
  );

  totalDistance += distance;
  previousMousePosition = currentMousePosition;

  const distanceInKilometers = totalDistance / 1000000;
  console.log(`Mouse has traveled: ${distanceInKilometers.toFixed(6)} km`);
}, 100);
