在ReactJs中,可以通过以下几种方式来避免代码重复:
// Button.js
import React from 'react';
const Button = ({ text }) => {
  return ;
};
export default Button;
// 使用Button组件
import React from 'react';
import Button from './Button';
const App = () => {
  return (
    
      
      
    
  );
};
export default App;
// withLogging.js
import React from 'react';
const withLogging = (WrappedComponent) => {
  return class extends React.Component {
    componentDidMount() {
      console.log('Component has mounted.');
    }
    render() {
      return // 使用withLogging高阶组件
import React from 'react';
import withLogging from './withLogging';
const Button = ({ text }) => {
  return ;
};
const ButtonWithLogging = withLogging(Button);
const App = () => {
  return // ShowText.js
import React from 'react';
const ShowText = ({ text }) => {
  return {text};
};
export default ShowText;
// 使用Render Props
import React from 'react';
import ShowText from './ShowText';
const TextContainer = ({ render }) => {
  const text = 'Hello World';
  return {render(text)};
};
const App = () => {
  return (
     {
        return  通过以上三种方式,可以有效地避免代码重复,提高代码的可维护性和复用性。
