TypeScript中PureComponent的可选默认属性

import React, { PureComponent } from 'react';

interface MyComponentProps {
  name: string;
  age?: number;
}

class MyComponent extends PureComponent<MyComponentProps> {
  static defaultProps = {
    age: 18,
  };

  render() {
    const { name, age } = this.props;
    return (
      <div>
        <p>Name: {name}</p>
        <p>Age: {age}</p>
      </div>
    );
  }
}

export default MyComponent;

import React from 'react';
import MyComponent from './MyComponent';

function App() {
  return <MyComponent name="John" />;
}

export default App;
