By default, if there's only one argument and it's a [primitive](https://developer.mozilla.org/en-US/docs/Glossary/Primitive), it's used directly as a key, otherwise it's all the function arguments JSON stringified as an array.\n\nYou could for example change it to only cache on the first argument `x => JSON.stringify(x)`.\n\n##### cache\n\nType: `Object`<br>\nDefault: `new Map()`\n\nUse a different cache storage. Must implement the following methods: `.has(key)`, `.get(key)`, `.set(key, value)`, and optionally `.clear()`. You could for example use a `WeakMap` instead.\n\n### mem.clear(fn)\n\nClear all cached data of a memoized function.\n\n#### fn\n\nType: `Function`\n\nMemoized function.\n\n\n## Tips\n\n### Cache statistics\n\nIf you want to know how many times your cache had a hit or a miss, you can make use of [stats-map](https://github.com/SamVerschueren/stats-map) as a replacement for the default cache.\n\n#### Example\n\n```js\nconst mem = require('mem');\nconst StatsMap = require('stats-map');\nconst got = require('got');\n\nconst cache = new StatsMap();\nconst memGot = mem(got, {cache});\n\nmemGot('sindresorhus.com')\n\t.then(() => memGot('sindresorhus.com'))\n\t.then(() => memGot('sindresorhus.com'));\n\nconsole.log(cache.stats);\n//=> {hits: 2, misses: 1}\n```\n\n\n## License\n\nMIT © [Sindre Sorhus](https://sindresorhus.com)\n",
