【问题描述】：

我在 javascript 中有这个数组：

cars = [
  color: red, type: sedan, name: ferrari,
  color: blue, type: sedan, name: ferrari,
  color: yellow, type: sedan, name: ferrari,
  color: red, type: coupe, name: toyota,
  color: red, type: sedan, name: toyota
]

我要做的是创建一个多维数组，其中我有第一个数组的信息，但它看起来像这样：

我想把法拉利和丰田分开

carsseparated[0] = [
  color: red, type: sedan, name: ferrari,
  color: blue, type: sedan, name: ferrari,
  color: yellow, type: sedan, name: ferrari
]

carsseparated[1] = [
  color: red, type: coupe, name: toyota,
  color: red, type: sedan, name: toyota
]

这是我一直在编写的代码

$scope.carsseparated= [];
var cont = 0;
$.each($scope.cars, function (index,value) 
  $scope.carsseparated[cont] = [value.color, value.type, value.name]
  cont = cont+1;

【参考方案1】：

let cars = [color: "red", type: "sedan", name: "ferrari", color: "blue", type: "sedan", name: "ferrari", color: "yellow", type: "sedan", name: "ferrari", color: "red", type: "coupe", name: "toyota",
            color: "red", type: "sedan", name: "toyota"];

let  car1 = cars.filter(val => val.name === 'ferrari');
let  car2 = cars.filter(val => val.name === 'toyota');
console.log(car1)

【讨论】：

是的，我想这可能行得通，但我正试图让它动态化，我想说的是，我不想这样做：val.name === 'ferrari ' 谢谢你的回答。
