Answer
Module pattern encapsulates private variables using closures.
Exposes only public methods, preventing namespace pollution.
Quick Answer
Module Pattern uses a closure (often IIFE) to create private state and expose only selected methods. const counter = (function() { let count = 0; return { increment() { count++ }, get() { return count } } })() — count is private, increment and get are public. Before ES6 modules, this was the standard encapsulation technique.
