javascript - 如何在 JavaScript 中最有效地对带有日期时间的字典数组进行合并和排序？

Question

假设我有以下 3 个数组，它们按 exercisedateandtime 升序排序:

var listA = [
  {name: "Mike", exercisedateandtime: 1299233593000, exercise: "Jumping Jacks"}, 
  {name: "Mike", exercisedateandtime: 1299237012000, exercise: "Running"}
];

var listB = [
  {name: "Charles", exercisedateandtime: 1299233712000, exercise: "Swimming"},
  {name: "Charles", exercisedateandtime: 1299233831000, exercise: "Swimming"},
  {name: "Charles", exercisedateandtime: 1299240620000, exercise: "Swimming"}
];

var listC = [
{name: "William", exercisedateandtime: 1299237320000, exercise: "Fishing"},
{name: "William", exercisedateandtime: 1299237611000, exercise: "Motor Boating"},
{name: "William", exercisedateandtime: 1299305420000, exercise: "Cycling"}
];

合并这些列表的最有效方法是什么，以便我得到的结果数组listD也按exercisedateandtime升序排序？是否可以创建一个接受任意数量数组的函数？ (注意:虽然提供的样本很小，但理想的方法应该是处理大型列表。)

var listD = [
{name: "Mike", exercisedateandtime: 1299233593000, exercise: "Jumping Jacks"},
{name: "Charles", exercisedateandtime: 1299233712000, exercise: "Swimming"},
{name: "Charles", exercisedateandtime: 1299233831000, exercise: "Swimming"},
{name: "Mike", exercisedateandtime: 1299237012000, exercise: "Running"},
{name: "William", exercisedateandtime: 1299237320000, exercise: "Fishing"},
{name: "William", exercisedateandtime: 1299237611000, exercise: "Motor Boating"},
{name: "Charles", exercisedateandtime: 1299240620000, exercise: "Swimming"},
{name: "William", exercisedateandtime: 1299305420000, exercise: "Cycling"}
];

Answer 1

var listD = listA.concat(listB, listC).sort(function(a, b) {
    return a.exercisedateandtime - b.exercisedateandtime
});
