// ABOUT THIS:
// This script above is just a small showcase of the Proxy powers

// When you verify an object's properties and subproperties
// Sometimes you are caught in a web of recursive conditions. Like:
//   if (obj && obj.sub && obj.sub.subsub && obj.sub.subsub.final) { ... }

// With the script above you can just do:
//   const pObj = proxyStructure(obj);
//   if (pObj.sub.subsub.final) { ... }
// Bear in mind this has a limitation of 3 sublevels,
// although it can be easily extended
