JavaScript aimed to be flexible, lightweight and fast.\n\n- [Install](#install)\n- [Usage](#usage)\n- [Performance](#performance)\n- [More examples](#more-examples)\n- [Contributing](#contributing)\n- [Support](#support)\n\n## Install\n\n```bash\nnpm install @alvarocastro/quicksort\n```\n\n## Usage\n\n```js\nconst sort = require('@alvarocastro/quicksort');\n\nconst elements = [8, -1, 3, 0.5, 200];\nsort(elements);\n// =\u003e [-1, 0.5, 3, 8, 200]\n```\n\n### sort(elements[, compare[, getPivot]])\n\nReturns a new sorted array based on the `compare` function criteria.\n\n#### elements\n\nType: `Array`\n\nList of elements to sort.\n\n#### compare\n\nType: `Function`\u003cbr\u003e\nDefault: [comparatorAscending](utils.js#L2)\n\nThe function to use to compare two elements and find their sorting order.\nThe expected return of the function is:\n* `-1` to sort the element to the left.\n* `1` to sort the element to the right.\n* `0` when the elements are the same, no sorting is made.\n\nA descending function is also provided in [utils.js](utils.js).\n\n#### getPivot\n\nType: `Function`\u003cbr\u003e\nDefault: [pickMiddleValue](utils.js#L20)\n\nThe function to use to pick a _pivot_ value from the array.\nThe expected return of the function is one element from the array being sorted.\n\n## Performance\n\nWant to test the performance?\n\nIncluded is the command `npm run performance` that will run a battery of profiled tests for your needs.\n\nHere is an example of the output (YMMV depending your hardware)\n```\nSorting random numbers generated in the range [-1,1]:\n#1 - 10 numbers\n\u003e Quicksort: 1ms\n\u003e Array.sort: 0ms\n#2 - 100 numbers\n\u003e Quicksort: 0ms\n\u003e Array.sort: 1ms\n#3 - 1000 numbers\n\u003e Quicksort: 10ms\n\u003e Array.sort: 1ms\n#4 - 10000 numbers\n\u003e Quicksort: 17ms\n\u003e Array.sort: 23ms\n#5 - 100000 numbers\n\u003e Quicksort: 162ms\n\u003e Array.sort: 422ms\n#6 - 1000000 numbers\n\u003e Quicksort: 1523ms\n\u003e Array.sort: 7164ms\n```\n\n## More examples\n\n### Reverse order\n\n```js\nconst sort = require('@alvarocastro/quicksort');\nconst {comparatorDescending} = require('@alvarocastro/quicksort/utils');\n\nconst elements = [8, -1, 3, 0.5, 200];\nsort(elements, comparatorDescending);\n// =\u003e [200, 8, 3, 0.5, -1]\n```\n\n### Custom elements\n\n```js\nconst sort = require('@alvarocastro/quicksort');\n\nconst elements = [\n\t{name: 'Sarah Connor', firstAppearance: 'The Terminator'},\n\t{name: 'T-800', firstAppearance: 'The Terminator'},\n\t{name: 'Kyle Reese', firstAppearance: 'The Terminator'},\n\t{name: 'John Connor', firstAppearance: 'Terminator 2: Judgement Day'},\n\t{name: 'T-1000', firstAppearance: 'Terminator 2: Judgement Day'}\n];\nconst comparator = function (a, b) {\n\tif (a.name \u003c b.name) {\n\t\treturn -1;\n\t} else if (a.name \u003e b.name) {\n\t\treturn 1;\n\t}\n\treturn 0;\n};\nsort(elements, comparator);\n// =\u003e [\n// {name: 'John Connor', firstAppearance: 'Terminator 2: Judgement Day'},\n// {name: 'Kyle Reese', firstAppearance: 'The Terminator'},\n// {name: 'Sarah Connor', firstAppearance: 'The Terminator'},\n// {name: 'T-800', firstAppearance: 'The Terminator'},\n// {name: 'T-1000', firstAppearance: 'Terminator 2: Judgement Day'}\n// ]\n```\n\n## Contributing\n\nContributions are always welcome!
