makeCache allows you to generate caching objects with timed expirey and LRU eviction.

Examples:

// Items can expire var cache = makeCache(); cache.get('a'); // => undefined cache.set('a', 1, {expireIn:1000}); cache.get('a'); // => 1 setTimeout(function(){ cache.get('a'); // => undefined }, 1100);

// Caches can be limited in size // Least-recently-used items will evict automatically var smallCache = makeCache({limit:2}); smallCache.set('a', 1); smallCache.get('a'); // => 1 smallCache.set('b', 2); smallCache.set('c', 3); smallCache.get('a'); // => undefined
