从平面对象数组创建嵌套对象数组（最多 5 层）
我需要从平面对象数组创建一个嵌套的对象数组，它最多有 5 个级别。原始 JSON 如下所示：
[{
"code": "01",
"name": "Some name 1",
"level": "1"
}, {
"code": "01.1",
"name": "Some name 2",
"level": "2"
}, {
"code": "01.11",
"name": "Some name 3",
"level": "3"
}, {
"code": "01.11.1",
"name": "Some name 4",
"level": "4"
}, {
"code": "01.11.11",
"name": "Some name 5",
"level": "5"
}, {
"code": "01.11.12",
"name": "Some name 6",
"level": "5"
}]
新数组将在 Ant Design Tree组件中使用，因此它应该具有以下结构：
[
{
key: '01',
title: 'Some name 1',
children: [
key: '01.1'
title: 'Some name 2',
children: [
{
key: '01.11'
title: 'Some name 3',
children: [
{
key: '01.11.1'
title: 'Some name 4',
children: [
{
key: '01.11.11'
title: 'Some name 5'
},
{
key: '01.11.12'
title: 'Some name 6'
}
]
}
]
}
]
]
}
]
如何优化此功能以获得所需的结果？

您可以创建一个解决方案，该解决方案将使用level属性将当前对象推送到嵌套结构中的某个级别，并将其与引用和reduce方法结合起来。const data = [{"code":"01","name":"Some name 1","level":"1"},{"code":"01.1","name":"Some name 2","level":"2"},{"code":"01.11","name":"Some name 3","level":"3"},{"code":"01.11.1","name":"Some name 4","level":"4"},{"code":"01.11.11","name":"Some name 5","level":"5"},{"code":"01.11.12","name":"Some name 6","level":"5"}]const result = data.reduce((r, { level, ...rest }) => { const value = { ...rest, children: [] } r[level] = value.children; r[level - 1].push(value) return r;}, [[]]).shift()console.log(result)
