如何从字符串中获取特定单词的下两个单词？

function getNextTwoWords(str, targetWord) {
  // 将字符串拆分成单词数组
  const words = str.split(' ');

  // 找到目标单词的索引位置
  const targetIndex = words.findIndex(word => word === targetWord);

  // 获取目标单词的下两个单词
  const nextTwoWords = words.slice(targetIndex + 1, targetIndex + 3);

  // 将下两个单词合并成字符串
  const result = nextTwoWords.join(' ');

  return result;
}

// 示例用法
const sentence = "This is an example sentence to demonstrate the solution.";
const target = "example";
const nextTwoWords = getNextTwoWords(sentence, target);
console.log(nextTwoWords); // 输出 "sentence to"
