有人能告诉我将数组转换为树状结构的最有效方法吗？

var array= [
        {id: "1",     name: "header1"},
        {id: "2",     name: "header2"},
        {id: "1.1",   name: "subheader1.1"},
        {id: "1.2",   name: "subheader1.2"},
        {id: "2.1",   name: "subheader2.1"},
        {id: "2.2",   name: "subheader2.2"},
        {id: "1.1.1", name: "subheader1detail1"},
        {id: "2.1.1", name: "subheader2detail2"}
];

结果数组必须如下:

var array = [{
    id: "1",
    name: "header1",
    items: [{
        id: "1.1",
        name: "subheader1.1",
        items: [{
            id: "1.1.1",
            name: "subheader1detail1",
        }]
    }, {
        id: "1.2",
        name: "subheader1.2"
    }]
}, {
    id: "2",
    name: "header2",
    items: [{
        id: "2.1",
        name: "subheader2.1",
        items: [{ …
