Setup

function generateRandomRules(count) {
  const types = ["custom", "default"];
  const rules = [];

  for (let i = 0; i < count; i++) {
    const rule = {
      name: `Rule${i + 1}`,
      type: types[Math.floor(Math.random() * types.length)], // Randomly assigns "custom" or "default"
      disabled: Math.random() > 0.5 // Randomly assigns true or false
    };
    rules.push(rule);
  }

  return rules;
}

const rules = generateRandomRules(100);
