What is the key difference between using Map and a plain JavaScript object for hash table implementation?
The distinction between Map and plain objects is significant because: 1) Maps can use any value type as keys, including objects and functions, 2) Objects convert all keys to strings or symbols, 3) Maps maintain insertion order while objects don't guarantee order, 4) Maps have built-in methods for size and iteration, 5) Maps don't inherit properties from Object.prototype, 6) Maps are designed specifically for frequent additions/removals, 7) Maps provide better performance for large sets of key-value pairs, 8) Maps are more suitable for implementing pure hash tables.
