es6 数组的常用算法

1.根据id删除指定元素，findIndex返回结果布尔值

this.prizes.splice(this.prizes.findIndex(e => e.id === this.prizeId), 1)

2.根据条件过滤数组元素，filter返回结果是数组

  this.radioList = res.data.filter(e=>e.channelEnableStatus !== 0)

4.根据数组里面数据的日期进行排序

arrData = arrData .sort((a,b)=>Date.parse(b.publishTime.replace(/-/g,"/"))-Date.parse(a.publishTime.replace(/-/g,"/")))

5.扩展运算扩展运算符和Set结构相结合，就可以去除数组的重复成员

let arr = [3, 5, 2, 2, 5, 5]; let unique = [...new Set(arr)]; // [3, 5, 2]
