How to move objects in JS?

Type, I have a Json 

{
  children":[
    {}
  ]
}

The question is, that sometimes there are objects inside objects and sometimes not, within that children, I can have other children, and so on.

Here's a suggestion: 

function criarSubPasta(obj, parent) {
  // criar <li>nome</li>
  var nameLi = document.createElement('li'); 
  nameLi.innerHTML = obj.name;
  parent.appendChild(nameLi);

  // parar aqui se não houver children
  if (!obj.children) return;

  // preparar um novo <ul></ul> para as subpastas
  var childrenLi = document.createElement('li');
  var ul = document.createElement('ul');
  parent.appendChild(childrenLi);
  childrenLi.appendChild(ul);
  obj.children.forEach(function(child) {
    // correr a mesma lógica recursivamente nas subpastas
    criarSubPasta(child, ul);
  });
}

criarSubPasta(json, document.querySelector('ul'));

Example: 

var json = [{
