**將一個(gè)沒有層級(jí)的扁平對(duì)象，轉(zhuǎn)換為樹形結(jié)構(gòu)**

let data = [{
"province": "浙江",
"city": "杭州",
"name": "西湖"
}, {
"province": "四川",
"city": "成都",
"name": "錦里"
}, {
"province": "四川",
"city": "成都",
"name": "方所"
}, {
"province": "四川",

轉(zhuǎn)換成如下數(shù)據(jù)結(jié)構(gòu)：
~~~
let tree = [{
"value": "浙江",
"children": [{
"value": "杭州",
"children": [{
"value": "西湖"
}]
}]
}, {
"value": "四川",
"children": [{
"value": "成都",
"children": [{
"value": "錦里"
}, {
"value": "方所"
}]
}, {
"value": "阿壩",
"children": [{
"value": "九寨溝"
}]
}]
}]
