Usage\nSorting three restaurants by `note` and `distance` fields:\n\n```js\nconst weightSum = require('weighted-sum')\nconst data = [\n  {\n    id: 'restaurant 1',\n    note: 4,\n    distance: 626\n

sortOptions)\n```\n\n## API\n\n### weightSum(data, sortOptions)\n\n#### data\nType: `Array`  \n- id field is **mandatory**\n- Sorting criterias must be numbers\n\n#### sortedOptions\n\nType: `Object`  \n- `includeScore`: whether or not include sorting score in result. Default is `false`\n- `weight` is **mandatory**\n- sum of all `weight` must equal 1\n- Default `sort` is `asc`\n\n## License\n\nMIT © [Dorian Camilleri](https://github.com/dcamilleri\u003e)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdcamilleri%2Fweighted-sum","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdcamilleri%2Fweighted-sum","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdcamilleri%2Fweighted-sum/lists"}
