javascript - Concat 两个数组，其中一个也是一个数组

Question

我如何连接两个数组，其中一个也是一个数组。看起来像这样

let stat = [
  ["completed", "0", "0", "0"],
  ["due", "1", "2", "2"],
  ["warning", "0", "0", "0"]
]

let val = [
  [0, 0, 0],
  [1, 2, 2],
  [0, 0, 0]
]



var arr = [];
for (var i = 0; i < stat.length; i++) {
  var temp = [stat[i][0].concat([val[i]])];
  arr.push(temp);
}
console.log(arr)

当console.log时，会打印出:

["Completed0,0,0"]
["Due1,2,2"]
["Warning0,0,0"]

我希望结果如下所示:

["Completed", 0, 0, 0]
["Due", 1, 2, 2]
["Warning", 0, 0, 0]

我怎样才能得到这样的新数组？谢谢!

let stat = [
  ["completed", "0", "0", "0"],
  ["due", "1", "2", "2"],
  ["warning", "0", "0", "0"]
]

let val = [
  ["0", "0", "0"],
  ["1", "2", "2"],
  ["0", "0", "0"]
]


var arr = [];
for (var i = 0; i < stat.length; i++) {
  var temp = stat[i].concat(
    val[i].filter(x => !stat[i].includes(x))
  );
  arr.push(temp);
}
console.log(arr);
