Status](https://img.shields.io/appveyor/ci/jonschlinkert/falsey.svg?style=flat\u0026label=AppVeyor)](https://ci.appveyor.com/project/jonschlinkert/falsey)\n\n\u003e Returns true if the given is falsey (according to JavaScript) or matches a 'falsey' keyword.\n\nPlease consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.\n\n## Install\n\nInstall with [npm](https://www.npmjs.com/):\n\n```sh\n$ npm install --save falsey\n```\n\n## What is this?\n\nThis is intended to be a fun way of accepting alternatives to `false` or \"no\" in CLI prompts, web forms, etc. For example, you might want to allow users to define `nil` or `nope` to disable something.\n\n## Usage\n\n```js\nconst falsey = require('falsey');\n\nconsole.log(falsey());       //=\u003e true\nconsole.log(falsey(false));  //=\u003e true\nconsole.log(falsey('nil'));  //=\u003e true\nconsole.log(falsey('nope')); //=\u003e true\nconsole.log(falsey('yes'));  //=\u003e false\n```\n\n## Examples\n\nAny value that is not falsey (according to JavaScript) _and is not in the list_ of [falsey keywords](#falsey-keywords) will return `false`:\n\n```js\nfalsey('abc');\nfalsey(true);\nfalsey(1);\nfalsey('1');\nfalsey({});\nfalsey([]);\n```\n\nAny value that is falsey (according to JavaScript) _or is in the list_ of [falsey keywords](#falsey-keywords) will return `true`:\n\n```js\nfalsey();          //=\u003e true\nfalsey('');        //=\u003e true\nfalsey(0);         //=\u003e true\nfalsey(false);     //=\u003e true\nfalsey(NaN);       //=\u003e true\nfalsey(null);      //=\u003e true\nfalsey(undefined); //=\u003e true\nfalsey(void 0);    //=\u003e true\n```\n\n### Falsey keywords\n\nIf a value matches one of the built-in \"falsey\" keywords (all strings) it will return `true`:\n\n* `0`\n* `false`\n* `nada`\n* `nil`\n* `nay`\n* `nah`\n* `negative`\n* `no`\n* `none`\n* `nope`\n* `nul`\n* `null`\n* `nix`\n* `nyet`\n* `uh-uh`\n* `veto`\n* `zero`\n\n**Customize falsey keywords**\n\nPass an array of custom keywords that should return `true` when evaluated as _falsey_:\n\n```js\nfalsey('zilch', ['no', 'nope', 'nada', 'zilch']); //=\u003e true\n```\n\nDisable built-in keywords by passing an empty array:\n\n```js\nfalsey('nil', []); //=\u003e false\n```\n\n**Extend built-in keywords**\n\nBuilt-in keywords are exposed on the `.keywords` property so that you may extend them with your own keywords:\n\n```js\nfalsey('zilch', falsey.keywords.concat(['zilch'])); //=\u003e true\n```\n\n## Release history\n\n### v1.0\n\n**Breaking changes**\n\n* objects will now always returns `false`\n* more words were added to the built-in list of [falsey keywords](#falsey-keywords)\n\n## About\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eContributing\u003c/strong\u003e\u003c/summary\u003e\n\nPull requests and stars are
