• When are JavaScript objects destroyed? 4 answers

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 well of hope. How do you execute stuff upon instance destruction?

MDN is a nice resource for JS. No, there is nothing like calling a function when an object ceases.
