Object.eval()? Really? What is this, a horror movie where the code comes to life? Object.freeze() is the way to keep those properties under control.

Finally, a question that doesn't involve baking cupcakes or managing a lemonade stand. Object.freeze() is the obvious choice here, folks.

I've used Object.freeze() before, it's great for preventing changes to objects.

Hey, Object.lock()? That sounds like something my grandpa would use to keep his diary safe. Let's go with the modern approach, Object.freeze()!

Hmm, Object.const() sounds like it might be the answer, but I don't think that's a real method. Better stick with the tried and true Object.freeze().

Object.freeze() is the way to go! Locks down those properties and keeps them pristine.

Object.lock() doesn't actually exist, so it can't be used for this requirement.
