    Determines the cache key for storing the result based on the function arguments. By default, __only the first argument is considered__ and it only works with [primitives](https://developer.mozilla.org/en-US/docs/Glossary/Primitive).

A `cacheKey` function can return any type supported by `Map` (or whatever structure you use in the `cache` option).

You can have it cache **all** the arguments by value with `JSON.stringify`, if they are compatible:

```
    import mem = require('mem');

mem(function_, {cacheKey: JSON.stringify});
    ```

Or you can use a more full-featured serializer like [serialize-javascript](https://github.com/yahoo/serialize-javascript) to add support for `RegExp`, `Date` and so on.

```
    import mem = require('mem');
    import serializeJavascript = require('serialize-javascript');

mem(function_, {cacheKey: serializeJavascript});
    ```

@default arguments_ => arguments_[0]
    @example arguments_ => JSON.stringify(arguments_)
