如何使用react和正则表达式将字符串中的模式替换为其他字符串？

import React from 'react';

class MyComponent extends React.Component {
  replacePatternInString = (pattern, replacement, inputString) => {
    const regex = new RegExp(pattern, 'g');
    return inputString.replace(regex, replacement);
  }

  render() {
    // ...
  }
}

render() {
  const inputString = 'This is a test string.';
  const pattern = 'test';
  const replacement = 'example';

  const replacedString = this.replacePatternInString(pattern, replacement, inputString);

  return (
    <div>
      <p>Original String: {inputString}</p>
      <p>Replaced String: {replacedString}</p>
    </div>
  );
}
