Since I've dealt in the past with javascript's funky "object model", I assume there is no such thing as a destructor. My searches were mildly unsuccessful, so you guys are my last hope. How do you execute stuff upon instance destruction?

The object destructuring is a useful JavaScript feature to extract properties from objects and bind them to variables. What's better, object destructuring can extract multiple properties in one statement, can access properties from nested objects, and can set a default value if the property doesn't exist.
Destructuring is the process of breaking a structure. In the context of programming, the structures are the data structures, and destructuring these data structures means unpacking individual values from the data structure. In JavaScript, destructuring can be applied to an Object or an Array.
A destructor is called for a class object when that object passes out of scope or is explicitly deleted. A destructor is a member function with the same name as its class prefixed by a ~ (tilde). For example: class X { public: // Constructor for class X X(); // Destructor for class X ~X(); };
MDN is a nice resource for JS. No, there is nothing like calling a function when an object ceases.
