javascript - 将对象转换为二维数组但删除键

Question

我正在尝试转换以下内容:

let JSON = [
    {1:"hello",2:"goodbye",3:"bonjour"},
    {4:"hello2",5:"goodbye2",6:"bonjour2"},
    {7:"hello3",8:"goodbye3",9:"bonjour3"},
    {10:"hello4",11:"goodbye4",12:"bonjour4"}
]

对此:

let arr = [
    ["hello","goodbye","bonjour"],
    ["hello2","goodbye2","bonjour2"],
    ["hello3","goodbye3","bonjour3"],
    ["hello4","goodbye4","bonjour4"]
]

我已经尝试过:

var row1 = JSON.map(function(e) {
    return [ e.1, e.2, e.3];
});
var row2 = JSON.map(function(e) {
    return [ e.4, e.5, e.6];
});
var row3 = JSON.map(function(e) {
    return [ e.7, e.8, e.9];
});
var row4 = JSON.map(function(e) {
    return [ e.10, e.11, e.12];

let array = [row1,row2,row3,row4] 

但无法让任何东西发挥作用。我将不胜感激任何帮助:)

试试这个:

let JSON = [
  {1:"hello",2:"goodbye",3:"bonjour"},
  {4:"hello2",5:"goodbye2",6:"bonjour2"},
  {7:"hello3",8:"goodbye3",9:"bonjour3"},
  {10:"hello4",11:"goodbye4",12:"bonjour4"}
];

let arr = JSON.map(obj => {
  return Object.values(obj);
});
