What does the following snippet demonstrate? const memoize = fn => { const cache = new Map(); return (…args) => { const key = JSON.stringify(args); if (cache.has(key)) return cache.get(key); const result = fn(…args); cache.set(key, result); return result; }; };

What does the following snippet demonstrate? const memoize = fn => { const cache = new Map(); return (…args) => { const key = JSON.stringify(args); if (cache.has(key)) return cache.get(key); const result = fn(…args); cache.set(key, result); return result; }; };

Key points

The function uses a Map to store results based on argument keys
It returns cached results if the same arguments are passed again
This technique helps optimize performance by avoiding recomputation
The function is a form of memoization to enhance efficiency
