这很简单。你可以使用.some()函数，如果回调函数中传递的条件与任何值匹配，它将返回true，否则将返回false。例如：

const string = "test!!";
const answers = ["Rock", "Paper", "Scissors"];

console.log(answers.some((val) => string.includes(val.toLowerCase())));

如果你想在filter中使用for循环，你可以尝试这样做：

const answers = ["Rock", "Paper", "Scissors"];
const filter = msg => {
  for (let answer of answers) {
    if (msg.content.includes(answer)) {
      return true;
    }
  }
  return false;
}

这将检查消息内容中是否包含任何答案，而不是检查是否完全匹配。您也可以使用Array.some()方法来简化代码：

const answers = ["Rock", "Paper", "Scissors"];
const filter = msg => answers.some(answer => msg.content.includes(answer));
