\r\n FrequencySet\r\n

\r\n\r\n

\r\n An ES6 Set compliant structure that keeps the frequency of occurrences.\r\n

\r\n\r\n## Requirements\r\n- [Node.js](https://nodejs.org/en/) v22 or higher\r\n\r\n## Getting Started\r\n\r\nThis package is available in the Node Package Repository and can be easily installed with [npm](https://docs.npmjs.com/getting-started/what-is-npm) or [yarn](https://yarnpkg.com).\r\n\r\n```bash\r\n$ npm i frequency-set\r\n# or\r\n$ yarn add frequency-set\r\n```\r\n\r\n## Usage example\r\n\r\n```js\r\nconst FrequencySet = require(\"frequency-set\");\r\n\r\nconst MySet = new FrequencySet([\"foo\", \"bar\"]);\r\nMySet.add(\"foo\");\r\nMySet.add(\"foo\");\r\nMySet.add(\"bar\");\r\n\r\nconsole.log([...MySet.entries()]); // [[\"foo\", 3], [\"bar\", 2]]\r\n\r\nconst clone = new FrequencySet(MySet);\r\nconsole.log(clone);\r\n```\r\n\r\n## API\r\nFrequencySet implements exactly the same interfaces as an ES6 [Set](https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Set). Except for the **@@ Iteration Symbol** and the **entries()**. Instead of returning the unique value as key and value, FrequencySet return the unique value as key and the count as value.\r\n\r\n```js\r\nconst mySet = new FrequencySet([\"foo\", \"foo\", \"bar\"]);\r\n\r\nfor (const [uniqueValue, count] of mySet) {\r\n console.log([uniqueValue, count]); // [foo, 2] and [bar, 1]\r\n}\r\n```\r\n\r\nAlso the add method has been extended with a additional `count` argument witch take a number.\r\n```js\r\nconst mySet = new FrequencySet().add(\"foo\", 10);\r\n\r\nconsole.log(mySet.toJSON()); // [\"foo\", 10]\r\n```\r\n\r\n### toJSON()\r\nFrequencySet implement a custom toJSON() method which will allow an automatic transformation into JSON.\r\n\r\n```js\r\nconst mySet = new FrequencySet([\"foo\", \"foo\", \"bar\"]);\r\n\r\nconsole.log(mySet.toJSON()); // [foo, 2] and [bar, 1];\r\n```\r\n\r\nThe toJSON method does not take into account **functions** and **objects**.\r\n\r\n## Contributors ✨\r\n\r\n\r\n[![All Contributors](https://img.shields.io/badge/all_contributors-1-orange.svg?style=flat-square)](#contributors-)\r\n\r\n\r\nThanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)):\r\n\r\n\r\n\r\n\r\n\r\n \r\n \r\n \r\n
