How can I emulate destructuring in C++?

I am afraid you cannot have it the way you are used to in JavaScript (which by the way seems to be new technology in JS). The reason is that in C++ you simply cannot assign to multiple variables within a structure/object/assignment expression as you did in

var {species, sound} = animal

and then use species and sound as simple variables. Currently C++ simply does not have that feature.

You could assign to structures and/or objects whilst overloading their assignment operator, but I don't see a way how you could emulate that exact behaviour (as of today). Consider the other answers offering similar solutions; maybe that works for your requirement.
