如何停止特定数量的javascript计数器

// 全局变量来存储计数器状态
var counterState = {
  stoppedCounters: 0
};

// 存储计数器实例的数组
var counters = [];

// 计数器构造函数
function Counter(id) {
  this.id = id;
  this.count = 0;
  
  // 每秒增加计数器值，并检查是否需要停止
  this.start = function() {
    var self = this;
    this.interval = setInterval(function() {
      self.count++;
      console.log("Counter " + self.id + " count: " + self.count);
      
      // 检查是否需要停止计数器
      if (self.count >= 10) {
        self.stop();
      }
    }, 1000);
  }
  
  // 停止计数器
  this.stop = function() {
    clearInterval(this.interval);
    counterState.stoppedCounters++;
    console.log("Counter " + this.id + " stopped");
  }
}

// 创建多个计数器实例
var counter1 = new Counter(1);
var counter2 = new Counter(2);
var counter3 = new Counter(3);

// 将计数器实例添加到数组中
counters.push(counter1, counter2, counter3);

// 启动所有计数器
counters.forEach(function(counter) {
  counter.start();
});

// 停止特定数量的计数器
var stopCount = 2;
counters.slice(0, stopCount).forEach(function(counter) {
  counter.stop();
});

// 输出已停止计数器的数量
console.log("Total stopped counters: " + counterState.stoppedCounters);
