秒表运行缓慢 - Javascript / Ember.js

Question

我有一个秒表，我作为一个ember.js控制器运行，它运行起来有点慢，所以随着时间的推移它落​​后了。试图确定如何最准确地加快速度。不确定这是由浏览器延迟引起的，还是系统不满意以此速度运行此过程。

//timer.js
import Ember from 'ember';

export default Ember.Controller.extend({

  state: 'reset',

  tick: 0,
  seconds: 0,
  minutes: 0,
  lapTime: 0,

  isResetState: Ember.computed.equal('state', 'reset'),
  isRunState: Ember.computed.equal('state', 'run'),
  isPauseState: Ember.computed.equal('state', 'pause'),
  isLapState: Ember.computed.equal('state', 'lap'),

  incrementTick(startDate) {
    let currentDate = new Date();
    if (this.get('isRunState') || this.get('isLapState')) {
      this.incrementProperty('tick', currentDate.valueOf() - startDate.valueOf());
      Ember.run.next(this, 'incrementTick', new Date());
    }
    if (this.tick > 999) {
      this.set('tick', 0);
      this.incrementProperty('seconds', 1);
    }
    if (this.seconds > 59) {
      this.set('seconds', 0);
      this.incrementProperty('minutes', 1);
    }
  },

  actions: {
    start() {
      this.set('state', 'run');
      this.incrementTick(new Date());
    },

    stop() {
      this.set('state', 'pause');
    },

    reset() {
      this.set('state', 'reset');
      this.set('tick', 0);
      this.set('seconds', 0);
      this.set('minutes', 0);
    },

    hold() {
      this.set('lapTime', this.get('tick'));
      this.set('state', 'lap');
    },

    continue() {
      this.set('state', 'run');
    },
  },
});
