消息推送系统

class Message {

constructor(id, importance, timestamp) {

this.id = id;

this.importance = importance; // 重要性得分

this.timestamp = timestamp; // 时间戳

}

}

function rankMessages(messages) {

return messages.sort((a, b) => {

const scoreA = a.importance + (Date.now() - a.timestamp);

const scoreB = b.importance + (Date.now() - b.timestamp);

return scoreB - scoreA; // 降序排列

});

}

// 示例使用

const messages = [

new Message(1, 5, Date.parse("2023-01-01")),

new Message(2, 7, Date.parse("2023-01-02")),

new Message(3, 6, Date.parse("2023-01-03"))

];

const rankedMessages = rankMessages(messages);

console.log(rankedMessages);
