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

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().

I agree with Maxima. Object.freeze() is the correct method to prevent properties from being modified.

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