关于前端:数组中删除一个或者多个数组对象

   var arr1 = [      {a: "111", b:"222",c:1,d:6},      {a:"333", b:"444",c:11,d:56},      {a:"555", b: "666",c:21,d:46},      {a: "777", b:"888",c:13,d:36},      {a:"999", b:"000",c:14,d:26},      {a:"110", b: "220",c:51,d:16}    ]    var arr2 = [    {a:"333", b:"444",c:11,d:56},      {a:"555", b: "666",c:21,d:46},      {a: "777", b:"888",c:13,d:36},      {a:"999", b:"000",c:14,d:26},          ]    function removeList(originList, delList) {      var newArr = originList      delList.forEach((Element1, index1) => {        originList.forEach((Element2, index2) => {          if (isObjectValueEqual(Element1, Element2)) {            newArr.splice(index2, 1)          }        })      })      originList = newArr      return originList    }    function isObjectValueEqual(a, b) {      var aProps = Object.getOwnPropertyNames(a);      var bProps = Object.getOwnPropertyNames(b);      if (aProps.length != bProps.length) {        return false;      }      for (var i = 0; i < aProps.length; i++) {        var propName = aProps[i]        var propA = a[propName]        var propB = b[propName]        if ((typeof (propA) === 'object')) {          if (this.isObjectValueEqual(propA, propB)) {            return true          } else {            return false          }        } else if (propA !== propB) {          return false        } else { }      }      return true    }    console.log(removeList(arr1,arr2));// 不扭转原数组的状况    console.log(removeList(JSON.stringify(arr1),arr2));
