const createCache = require('lodash._createcache'); // In Lodash v3, a cache created by `createCache` typically provided // methods like `get`, `set`, and `has`. This example demonstrates // a simplified usage pattern for an internal cache. const memoizationCache = createCache(); function expensiveCalculation(value) { const cacheKey = String(value); if (memoizationCache.has(cacheKey)) { console.log(`Cache hit for key: ${cacheKey}`); return memoizationCache.get(cacheKey); } console.log(`Cache miss for key: ${cacheKey}, performing expensive calculation...`); const result = value * value * 3.14159; // Simulate heavy computation memoizationCache.set(cacheKey, result); return result; } console.log(`Result for 10: ${expensiveCalculation(10)}`); // Cache miss, compute console.log(`Result for 20: ${expensiveCalculation(20)}`); // Cache miss, compute console.log(`Result for 10: ${expensiveCalculation(10)}`); // Cache hit, retrieve // This illustrates direct interaction with the created cache object. // In actual Lodash v3, this would typically be used internally by `_.memoize`.
