seq\n\nA simple library for manipulating generators and arrays in JavaScript. \n\n[![Travis](https://img.shields.io/travis/njlr/seq.svg)](https://travis-ci.org/njlr/seq) \n\n## Get Started\n\nInstall using [Yarn](https://yarnpkg.com/): \n\n```bash\nyarn add @njlr/seq\n```\n\nInstall using [NPM](https://www.npmjs.com/): \n\n\n```bash\nnpm install --save @njlr/seq\n```\n\nYou can [browse the documentation on GitHub](https://njlr.github.io/seq/).\n\n\n## Why? 🤔\n\n * Some of the built-in Array functions are mutating (e.g. `Array.prototype.sort`). \n * Many array functions are missing. Where is `Array.prototype.flatMap`?\n * A chain of array functions creates a new array at every stage: the operations are not lazy. \n * [lodash](https://lodash.com/) and [friends](https://github.com/jussi-kalliokoski/trine) require either a wrapper object or binding for chaining calls. We use the [pipeline operator](https://github.com/babel/babel/tree/master/packages/babel-plugin-proposal-pipeline-operator) (`|\u003e`) to achieve this at compile-time! \n * This package is a good citizen. It has no dependencies and does not mutate any global objects. \n * The code is simple. You can review the whole thing in about an hour. \n\n## Demo\n\n```javascript\nimport * as seq from '@njlr/seq';\n\nconst xs = [ 1, 5, 1, 2, 7, 3, 3, 4, 5, 0 ] \n  |\u003e seq.unique()\n  |\u003e seq.map(x =\u003e x * 2)\n  |\u003e seq.filter(x =\u003e x \u003e 4)\n  |\u003e seq.sorted()\n  |\u003e seq.toArray;\n\n// xs is [ 6, 8, 10, 14 ]\n```\n\nSince seq works on iterables, you can also use `for...of` loops:\n\n```javascript\nimport * as seq from '@njlr/seq';\n\nfor (const x of seq.range(10) |\u003e seq.map(x =\u003e x * x)) {\n  console.log(x);\n}\n```\n\nThis library also plays nicely with spread syntax! \n\n```javascript\nconst squares = [ ... seq.range(10) |\u003e seq.map(x =\u003e x * x) ];\n```\n\n\n## Development\n\nDependencies are managed by Yarn: \n\n```bash\nyarn install --pure-lockfile\n```\n\nTo run all tests:\n\n```bash\nyarn test\n```\n\nTo build the library:\n\n```bash\nyarn build\n```\n\nTo build the documentation: \n\n```bash\nyarn docs\n```\n\nTo release a new version:\n\n```bash\nnpm publish --access public \n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnjlr%2Fseq","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnjlr%2Fseq","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnjlr%2Fseq/lists"}
