Hi FE ！

一、变量解构一解就报错优化前：

const App = (props) => {
  const { data } = props;
  const { name, age } = data
}

优化后：

const App = (props) => {
  const { data } = props;
  const { name, age } = data || {};
}

优化前

import React, { useState } from 'react';

const App = () => {
  const [loading, setLoading] = useState(false);
  const getData = async () => {
    setLoading(true);
    const res = await queryData();
    setLoading(false);
  }
}

优化后

import React, { useState } from 'react';
import to from 'await-to-js';

const App = () => {
  const [loading, setLoading] = useState(false);
  const getData = async () => {
    setLoading(true);
    const [err, res] = await to(queryData());
    setLoading(false);
  }
}
