js怎样将获取json转换为树形结构

比如这样一段json
{
"name":"1级菜单1",
"link":"###",
"isleaf": false,
"level": 0,
"children": [
{
"name":"2级菜单1",
"link":"###",
"isleaf": false,
"level": 1,
"children": [
{
"name":"3级菜单1",
"link":"###",
"isleaf": true,
"level": 2,
"children": null
},
{
"name":"3级菜单2",
"link":"###",
"isleaf": true,
"level": 2,
"children": null
}
]
},
{
"name":"2级菜单2",
"link":"###",
"isleaf": false,
"level": 1,
"children": [
{
"name":"3级菜单3",
"link":"###",
"isleaf": true,
"level": 2,
"children": null
}
]
}
]
}
