This example demonstrates a JavaScript class called `TreasureChest` that models a collection of gold, silver, and bronze coins. It shows how to initialize the chest with default values, add coins of each type using chainable methods like `addGold`, `addSilver`, and `addBronze`, and retrieve a summary via `getLoot`. A static `getRandomLoot` method uses a private `#shuffle` function to assign random coin counts. The visualization itself is minimal, with all interaction occurring through the browser console, using native JavaScript class syntax and no external libraries.
