console打印出来的数组长度不一样

Question

project.peopleList({            'projectId': that.id         }, function(data) {             console.log('data',data);            // 项目的所有参与人去掉项目负责人显示             that.peopleLists = [];//先清空，避免重复push             for(var i = data.length - 1; i>=0; i--){                if(data[i].peopleId == that.currentPeople){                    data.splice(i,1)                 }else{                     that.peopleLists.push(data[i]);                     that.$emit('update:peopleLists',that.peopleLists)                 }             }         })接口返回了3条数据，但是打印出的结果却是这样的去掉for循环显示正常，想知道这是什么原因导致的这样的现象，谢谢大家

chorme的console应该是是类似指针形式，就像对象赋值一样，一开始console出length是原本的长度，后来经过for之后删掉了一个，这时你在console点开data的值，的确只有两个。
