Stop the Hand Waving – Scope Chains & Closures

About this presentation

Scope Chains, Closures, Hoisting, and Garbage Collection all have one thing in common: They're often hand-waved away. How do closures actually work? When does Garbage Collection occur? What really IS the Scope Chain? In this talk, we will discover it's not black magic after all; No hand waving is required to explain these language features, in fact you've been using them all along without realising.
