[removed] Object Rename Key

Question

Is there a clever (i.e. optimized) way to rename a key in a javascript object?

A non-optimized way would be:

o[ new_key ] = o[ old_key ];
delete o[ o

Trying using lodash transform.

var _ = require('lodash');

obj = {
  "name": "abc",
  "add": "xyz"
};

var newObject = _.transform(obj, function(result, val, key) {

  if (key === "add") {
    result["address"] = val
  } else {
    result[key] = val
  }
});
console.log(obj);
console.log(newObject);
