\n\n[](https://travis-ci.org/sindresorhus/mimic-fn)\n\n> Make a function mimic another one\n\nUseful when you wrap a function in another function and like to preserve the original name and other properties.\n\n\n## Install\n\n```\n$ npm install mimic-fn\n```\n\n\n## Usage\n\n```js\nconst mimicFn = require('mimic-fn');\n\nfunction foo() {}\nfoo.unicorn = '🦄';\n\nfunction wrapper() {\n\treturn foo();\n}\n\nconsole.log(wrapper.name);\n//=> 'wrapper'\n\nmimicFn(wrapper, foo);\n\nconsole.log(wrapper.name);\n//=> 'foo'\n\nconsole.log(wrapper.unicorn);\n//=> '🦄'\n\nconsole.log(String(wrapper));\n//=> '/* Wrapped with wrapper() */\\nfunction foo() {}'\n```\n\n\n## API\n\n### mimicFn(to, from, options?)\n\nModifies the `to` function to mimic the `from` function. Returns the `to` function.\n\n`name`, `displayName`, and any other properties of `from` are copied. The `length` property is not copied. Prototype, class, and inherited properties are copied.\n\n`to.toString()` will return the same as `from.toString()` but prepended with a `Wrapped with to()` comment.\n\n#### to\n\nType: `Function`\n\nMimicking function.\n\n#### from\n\nType: `Function`\n\nFunction to mimic.\n\n#### options\n\nType: `object`\n\n##### ignoreNonConfigurable\n\nType: `boolean`
\nDefault: `false`\n\nSkip modifying [non-configurable properties](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertyDescriptor#Description) instead of throwing an error.\n\n## Related\n\n- [rename-fn](https://github.com/sindresorhus/rename-fn) - Rename a function\n- [keep-func-props](https://github.com/ehmicky/keep-func-props) - Wrap a function without changing its name and other properties\n\n\n---\n\n\n","readmeFilename":"readme.md"}
