This is familiar to programmers who are used to pointers or references. (Java's `final` does the same thing).
To prevent changes to an object's properties, you could use `Object.freeze()` instead [1]. NB, this is shallow, so a child object of a frozen object can still have its properties changed.
Thanks for the feedback! I did know about the pointer bit but for people unfamiliar this might come as a bit of a shock. I'm going to update the post. Hit me up on twitter if you'd like to be credited(@jacopotarantino) since I don't check in here very often.
Agreed - in fact, when writing services for Angular in ES6, I take advantage of the fact that I can define a function using const and then set the $inject propert of it.
