let timeout = null;
//防抖
const debounce = function (fn, wait) {
  if (timeout !== null) clearTimeout(timeout);
  timeout = setTimeout(fn, wait);
};
// async/await处理异常事件
const to = function (promise) {
  return promise
    .then((data) => {
      return [null, data];
    })
    .catch((err) => [err]);
};

export default {
  debounce,
  to,
};
