Renaming Keys in JavaScript Objects
Enhancing the efficiency of key renaming in JavaScript objects is a pertinent challenge for developers seeking optimization. While a simple approach involves reassigning the key's value and subsequently deleting the old key, a more refined solution exists.
The most comprehensive and accurate method involves utilizing object property definitions:
if (old_key !== new_key) { Object.defineProperty(o, new_key, Object.getOwnPropertyDescriptor(o, old_key)); delete o[old_key]; }
This approach guarantees that the renamed property retains the identical behavior as its original counterpart. Notably, there seems to be no significant advantage in encapsulating this functionality as a dedicated method in Object.prototype.
