Resurrecting the .destroy() function

example.js

  //PouchDB.destroy() is (going to be) deprecated by PouchDB, but the
  //semantics from db.destroy() differ when wrapped so re-add it.
  if (!(PouchDB.destroy || {}).isResurrected) {
    var orig = PouchDB.destroy;
    PouchDB.destroy = function (name, options, callback) {
      var args = parseBaseArgs(PouchDB, this, options, callback);

      //3.2.2 deprecates .destroy() and introduces opts.internal for as
      //long as PouchDB will still use the method internally (hopefully)
      if (!(PouchDB.version >= '3.2.2') || args.options.internal) {
        return orig.apply(this, arguments);
      }
      var db = new PouchDB(name, args.options);
      var promise = db.destroy();
      nodify(promise, args.callback);
      return promise;
    }
    PouchDB.destroy.isResurrected = true;
  }
