Delete Key\n[![Build Status](https://travis-ci.org/flexdinesh/del-key.svg?branch=master)](https://travis-ci.org/flexdinesh/del-key)\n[![npm version](https://badge.fury.io/js/del-key.svg)](https://www.npmjs.com/package/del-key)\n[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://opensource.org/licenses/MIT)\n\nDelete a key from a deeply nested JavaScript object.\n\n## Why? [![start with why](https://img.shields.io/badge/start%20with-why%3F-brightgreen.svg?style=flat)](http://www.ted.com/talks/simon_sinek_how_great_leaders_inspire_action)\n\nThere are a few other libs that already aid in deleting keys from objects. But none of them iteratively deletes the key if one of the nested objects is an _array_.\n\nThe following are the highlights of this `delete-key` library.\n  - Traverses through the exact path for maximum performance. Does not iterate over the keys to detect presence.\n  - Support for arrays in object path. Keys will be iteratively removed from each item in the array. *(This is where `del-key` differs from lodash's `_.unset()` method)*\n  - Accepts array index in path definition.\n  - Mutates the object.\n\n\n## Install\n\n```\n$ npm install --save del-key\n```\n\n## Usage\n\n### Syntax\n\n**deleteKey(obj, pathToDelete)**\n\n_obj_ - the object that has the key to be deleted\n\n_pathToDelete_ - the path to the key in the object in string notation\n\n_See examples below for more info_.\n\n\n### Examples\n\n```js\nimport deleteKey from 'del-key'; // ES6 style import\n// const deleteKey = require('del-key'); // ES5 style import\n\nconst obj = {\n  nestedKey: {\n    poorKey: 'hello',\n    luckyKey: 'hi'\n  }\n}\ndeleteKey(obj, 'nestedKey.poorKey') // =\u003eobj.nestedKey = { luckyKey: 'hi' }\n//------------------------------------\n\nconst obj = {\n  nestedArray: [{\n    poorKey: 'first hello',\n    luckyKey: 'first hi'\n  }, {\n    poorKey: 'second hello',\n    luckyKey: 'second hi'\n  }]\n}\ndeleteKey(obj, 'nestedArray[0].poorKey')\n// =\u003eobj.nestedArray[0] = { luckyKey: 'first hi' }\n// =\u003eobj.nestedArray[1] = { poorKey: 'second hello', luckyKey: 'first hi' }\n//------------------------------------\n\nconst obj = {\n  nestedArray: [{\n    poorKey: 'first hello',\n    luckyKey: 'first hi'\n  }, {\n    poorKey: 'second hello',\n    luckyKey: 'second hi'\n  }]\n}\ndeleteKey(obj, 'nestedArray.poorKey') // =\u003e iteratively removes poorKey from each item in nestedArray\n// =\u003eobj.nestedArray[0] = { luckyKey: 'first hi' }\n// =\u003eobj.nestedArray[1] = { luckyKey: 'first hi' }\n\n```\n\n\n## License\n\nMIT © Dineshkumar Pandiyan\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fflexdinesh%2Fdel-key","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fflexdinesh%2Fdel-key","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fflexdinesh%2Fdel-key/lists"}
