Make it, please

In the case of LoadFromFile, it would somehow be informed of the enum structure of "g_Vehicles", then save the data in a file also containing the key names (so the enum can be modified and data will still be loaded properly).
Saving enums automatically is actually currently doable, but only as raw data, which would be corrupted when the enum is modified (and it can't be manually modified unless you're a robot or a Y_Less).

Node.js is just like in the browser, but with different idioms and structuring (arguably). It's super-easy to get started with and lots of fun!
JSON is a JavaScript object stored as a string (essentially), so now you've learned all you need about JSON!
