javascript - 是否可以创建无限维 JavaScript 数组？

Question

我正在尝试在 JavaScript 中创建(或模拟)一个无限维数组。本质上，这将是一个将对象与整数列表(可以是任意长度)相关联的数据结构。有没有一种有效的方法来存储此数据结构中的每个元素？

function addElement(theObject, coordinates){
    //object is the object, and coordinates is the list of coordinates (any number of coordinates will be accepted, since it's infinite-dimensional)
}

function getObject(coordinates){
    //get the object that was previously assigned to this list of coordinates
}
addElement("Hello World", [0, 0, 3, 5]);
console.log(getObject([0, 0, 3, 5])); //this would print "Hello World".

Answer 1

除非有任何原因不能，否则我只会使用坐标作为索引，并将内容存储在那里:

var coordinates = [];
var testCoord = [0,0,3,5];
coordinates[testCoord] = "Hello World";
console.log(coordinates[testCoord]);
