React移动端性能优化指南：如何提升前端应用的响应速度和流畅度

import React, { PureComponent, memo } from 'react';

// 使用PureComponent优化类组件
class MyClassComponent extends PureComponent {
  render() {
    return (
      // 组件的渲染内容
    );
  }
}

// 使用memo优化函数式组件
const MyFunctionalComponent = memo((props) => {
  return (
    // 组件的渲染内容
  );
});

import React, { PureComponent } from 'react';
import { FixedSizeList as List } from 'react-window';

class MyList extends PureComponent {
  render() {
    return (
      <List
        height={200}
        itemCount={1000}
        itemSize={50}
        width={300}
      >
        {({ index, style }) => (
          <div style={style}>
            {/* 列表项的内容 */}
          </div>
        )}
      </List>
    );
  }
}

import React, { PureComponent } from 'react';

class MyComponent extends PureComponent {
  shouldComponentUpdate(nextProps) {
    // 只在属性改变时重新渲染组件
    if (this.props.someProp !== nextProps.someProp) {
      return true;
    }
    return false;
  }
  
  render() {
    return (
      // 组件的渲染内容
    );
  }
}

import React, { lazy, Suspense } from 'react';

const MyLazyComponent = lazy(() => import('./MyComponent'));

const App = () => (
  <Suspense fallback={<div>Loading...</div>}>
    <MyLazyComponent />
  </Suspense>
);
