Node.js var为循环nodejs获取[]外部

我有3个数组中的数据，我需要将所有数据连接到一个数组中，但我需要创建一个新数组，其中我有一个时间戳，x1，x2，x3，其中x1，x2，x3是每个数组的每个值

像live=1，repeated=2，passway=3一样，我将使用array=[时间戳，1，2，3]

我有我的阵列活，重复和价值观的过客

我不明白为什么数组inst充满了值。。。总是打印[]

var live=[];
var repeated=[];
var passerBy=[];
var data=[];
live=[["2017-07-22T14:39:21.000Z","836"],["2017-07-22T14:44:21.000Z","207"],["2017-07-22T14:49:21.000Z","2006"],["2017-07-22T14:54:21.000Z","402"],["2017-07-22T14:59:22.000Z","198"],["2017-07-22T15:04:22.000Z","597"],["2017-07-22T15:16:22.000Z","180"],["2017-07-22T15:21:22.000Z","138"],["2017-07-22T15:26:22.000Z","293"]];
repeated=[["2017-07-22T14:39:21.000Z","18"],["2017-07-22T14:44:21.000Z","1"],["2017-07-22T14:49:21.000Z","1"],["2017-07-22T14:54:21.000Z","1"],["2017-07-22T14:59:22.000Z","1"],["2017-07-22T15:04:22.000Z","9"],["2017-07-22T15:16:22.000Z","1"],["2017-07-22T15:21:22.000Z","2"],["2017-07-22T15:26:22.000Z","1"]];

    for(var l=0; l<live.length; l++){
        for(var r=0; r<repeated.length; r++){
            if(live[l][0] == repeated[r][0]){
                var aux = [];
                aux.push(live[l][0]);
                aux.push(live[l][1]);
                aux.push(repeated[r][1]);
                data.push(aux);
            }
        }
        console.log("data for 1 ",data);
    }

    console.log('array for 2', data);

    for(var p=0; p<passerBy.length;p++){
        for(var a=0; a<data.length; a++){
            if(passerBy[p][0] == data[a][0]){
                data[a].push(passerBy[p][1]);
            }
        }
    }

    console.log('array for 3', data);

    for(var a=0; a<data.length;a++){
        //array[a][0] = Date(array[a][0]).toString());

        data[a][0]=new Date(Date.parse(data[a][0]));
    }

    console.log('array for 4', data);

我已经运行了你的代码，它工作得很好。它可以使用（最新的）FF或node.js工作。但是我在我的项目中使用express，它不工作。。。
