Javascript Vue计算功能赢得'；无法编译语法错误

我的Vue代码中有一个计算元素无法编译，因为在

返回this.dataEvents的第3/4行有一个意外标记
.filter（dataEvent=>！this.filters.title

从逻辑上看，这应该是正确的，但它不会针对语法和令牌错误生成

我做错了什么

computed: {
  filtered() {
    return this.dataEvents
      .filter(dataEvent => !this.filters.title || dataEvent.title === this.filters.title),
      .filter(dataEvent => !this.filters.resource || dataEvent.resource === this.filters.resource),
      .filter(dataEvent => !this.filters.location || dataEvent.location === this.filters.location),
      .filter(dataEvent => !this.filters.status || dataEvent.status === this.filters.status);
  },

  titles() {
    return this.dataEvents.map(dataEvent => dataEvent.title)
      .filter((title, index, self) => self.indexOf(title) === index);
  },

  resources() {
    return this.dataEvents
      .map(dataEvent => dataEvent.resource)
      .filter((resource, index, self) => self.indexOf(resource) === index);
  },

  locations() {
    return this.dataEvents
      .map(dataEvent => dataEvent.location)
      .filter((location, index, self) => self.indexOf(location) === index);
  },

  statuses() {
    return this.dataEvents
      .map(dataEvent => dataEvent.status)
      .filter((status, index, self) => self.indexOf(status) === index);
  },
},

它不应该在

过滤器

之后添加逗号，啊，好的呼叫！这就解决了它，谢谢！
