Ep 7: Scope Chain & Lexical Environment

• Every EC has a reference to its lexical parent's environment — this chain is the Scope Chain.
• An inner function can access variables in all outer scopes; the global EC cannot access local variables.
• Lexical Environment = local memory + reference to parent's lexical environment.
• The search travels up the chain until null (global) is reached — this is lexical scoping.
