如何从 JavaScript 数组中删除元素？

Question

我想删除数组中的值，但我下面的代码不起作用：

stations=['stations1','stations2']
 wayPoints=[{location: "stations1"},{location: "stations2"},{location: "stations3"},{location: "stations4"}]
deletStations(){

let result=[];

this.stations.forEach(index1 => rest.push(this.arrayRemove(this.wayPoints,index1)) );

}

arrayRemove(arr, value) {

 return arr.filter(function(ele){
     return ele != value;
 });

}

上面的代码不会从 wayPoints 中删除{location: "stations1"}, {location: "stations2"} ，请问有什么建议吗？

Answer 1

这是一种方法：

const secondWayOfDoingIt = wayPoints.filter(
  element => !stations.includes(element.location)
);

同样，但具有解构的论点：

const firstWayOfDoingIt = wayPoints.filter(
  ({ location }) => !stations.includes(location)
);

希望能帮助到你。
