I want to delete parent element includes all children. When i have one child in parent element it works, but if there are 2 children, it doesn't work.

// **arr is data list**

const handleDelete = (arr, id) => {

    let newArr = [...arr];
    newArr = newArr.filter(item => item.id !== id);
    const children = newArr.filter(item => item.parentId === id);
    if (children.length > 0) {
      newArr = newArr.filter(item => item.parentId !== id);
      children.forEach(item => handleDelete(newArr, item.id));
      return;
    }
    dispatch(deleteList(newArr));
    return newArr;
  };
