遍历单词数组并返回新的数字数组

function convertWordsToNumbers(words) {
  const numbers = [];

  for (let i = 0; i < words.length; i++) {
    const word = words[i];
    const number = parseFloat(word); // 将单词解析为数字

    if (!isNaN(number)) {
      numbers.push(number); // 如果是有效的数字，添加到数字数组中
    }
    // 可以根据需求处理无法解析为数字的情况
  }

  return numbers;
}

// 示例用法
const words = ["3", "5", "hello", "9", "world"];
const numbers = convertWordsToNumbers(words);
console.log(numbers); // 输出: [3, 5, 9]
