### Features
* Works with any type of function arguments – **no serialization is needed**
* Works with [**any length of function arguments**](#arguments-length). Length can be set as fixed or dynamic.
* One of the [**fastest**](#benchmarks) available solutions.
* Support for [**promises**](#promise-returning-functions) and [**asynchronous functions**](#nodejs-callback-style-functions)
* [**Primitive mode**](#primitive-mode) which assures fast performance when arguments are convertible to strings.
* [**WeakMap based mode**](#weakmap-based-configurations) for garbage collection friendly configuration
* Can be configured [**for methods**](#memoizing-methods) (when `this` counts in)
* Cache [**can be cleared manually**](#manual-clean-up) or [**after specified timeout**](#expire-cache-after-given-period-of-time)
* Cache size can be **[limited on LRU basis](#limiting-cache-size)**
* Optionally [**accepts resolvers**](#argument-resolvers) that normalize function arguments before passing them to underlying function.
* Optional [**reference counter mode**](#reference-counter), that allows more sophisticated cache management
* [**Profile tool**](#profiling--statistics) that provides valuable usage statistics
* Covered by [**over 500 unit tests**](#tests)
