The JavaScript Interpreter, Interpreted
summary
Explains how JavaScript actually creates and executes function objects: a distinct creation phase builds a variable object (with arguments), hoisting pulls names up and sets locals to undefined, and an execution phase runs code; scope is a chain of variable objects linked to parents, there are three execution contexts (global, function, eval), this resolves to global for top-level, to the receiver for methods and to the new object for constructors, closures keep references to parent variable objects, with live demos like find the kitten and the b/puppycat method reassignment.
