如何通过检查 javascript 中的键 `status` 来更改嵌套数组 object

Question

I have a object obj , has nested array of object children , loop through each object and

check status and remove the object if status is deleted .

I have a code below, but partial works and each nested array may/maynot have any number children .

How to remove based on condition in javascript

removeList =(obj)=>{
  if (obj.length > 0) {
    var result = obj.map(e => {
      if('children' in e)
        e.children = e.children.map(child => {
          if ('children' in child) 
            child.children = child.children.filter(c =>
              c['status'] !== "Deleted"
            );
            return child;
        });      
      return e
    });
    return result;
  }


}
console.log(this.removeList);
var obj = [
  {
   id:1,
   children: [
     {id:1, name: "grocery", status:"active",children:[{id:4, name:"lentils", status:"active"}]},
     {id:2, name: "fruits", status:"deleted"},
     {id:3, name: "coffee", status:"inactive",
       children: [
        {id:6, name:"vegetables", status:"inactive"},
        {id:7, name:"greens", status:"deleted"}
       ]
     }
   ]
  }
]

Expected Output:

[
  {
   id:1,
   children: [
     {id:1, name: "grocery", status:"active",children:[{id:4, name:"lentils", status:"active"}]},
     {id:3, name: "coffee", status:"inactive",
       children: [
        {id:6, name:"vegetables", status:"inactive"}
       ]
     }
   ]

  }
]

You can use recursion for your solution. Here it is:

var obj = [
  {
   id:1,
   children: [
     {id:1, name: "grocery", status:"active",children:[{id:4, name:"lentils", status:"active"}]},
     {id:2, name: "fruits", status:"deleted"},
     {id:3, name: "coffee", status:"inactive",
       children: [
        {id:6, name:"vegetables", status:"inactive"},
        {id:7, name:"greens", status:"deleted"}
       ]
     }
   ]
  }
]

removeList =(obj)=>{
  if (obj.length > 0) {
    var result = []
    obj.forEach(e => {
      if(e.status !== "deleted") { 
        if(e.children && e.children.length > 0) { e.children = removeList(e.children); }
      
        result.push(e) 
      }
    });
    return result;
  }


}
console.log(removeList(obj));
