omnikit\n\nOmnikit is a JavaScript utility bundle, which contains `Optional` class, collections, math and so on.\n\nNote: First version contains only few features. I will add more features. Stay tuned.\n\n## Install(without Node.js / on Browsers)\n\nCopy `build/omnikit.min.js` into your project directory,\nand load the file from your HTML file.\n\n```\n\u003cscript src=\"omnikit.min.js\"\u003e\u003c/script\u003e\n\u003cscript\u003e\n  // Write your code here!\n\u003c/script\u003e\n```\n\nOther files(`lib`, `src`, etc.) are for Node.js, so you can ignore them.\n\n## Install(with Node.js)\n\nInstall omnikit into your project.\n\n```\nnpm install omnikit --save\n```\n\nThen import modules that you need. For example, `Optional`, `Stack` and `Random`.\n\n```\nconst { Optional, Stack, Random } = require('omnikit');\n```\n\n## Basic Usage\n\nFor details, see [API Document](https://kotofurumiya.github.io/omnikit/).\n\n### ranges\n\nomnikit provides python-like simple range iterator.\n\n```\nfor(const value of range(0, 10)) {\n  console.log(value); // 0, 1, 2, 3, ..., 9\n}\n```\n\nYou can also use more specific ranges.\n\n```\ninclusiveRange(0, 10); // 0, 1, 2, ..., 10\nexclusiveRange(0, 10); // 1, 1, 2, ..., 9\nopenClosedRange(0, 10); // 1, 2, 3, ..., 10\nclosedOpenRange(0, 10); // same as range(0, 10)\n```\n\nAll range functions receive 3rd argument as step.\n\n```\nrange(0, 10, 0.5); // 0, 0.5, 1.0, ..., 9.5\n```\n\nA step value can be negative.\n\nTo convert range to array, use `toArray()` method.\n\n```\nrange(0, 10).toArray();\n```\n\n### Optional\n\n`Optional` class represent nullable(undefinable) value, which is inspired by Java and Swift.\n\n```\nconst opt = new Optional('hello');\nconst opt2 = opt.map((val) =\u003e val + ' world');\nconst str = opt2.flatMap((val) =\u003e val);\nconsole.log(str); // hello world\n```\n\n### Random\n\n`Random` class generate random values with a seed.\n\n```\nconst random = new Random();\n// const randomWithSeed = new Random(12345);\n\nconsole.log(random.next());\nconsole.log(random.nextInt(5, 10)); // from 5 to 10\n```\n\n### conditions\n\n```\nconst cond1 = isNull(null); // true\nconst cond2 = isUndefined(undefined); // true\n```\n\n### Timer\n\n`Timer` class provides periodical execution.\n\n```\nconst timer = new Timer(1000); // every 1000ms\ntimer.addEventListener('tick', () =\u003e console.log('Hi');\ntimer.start();\n\n// To stop the timer, use stop method.\n// timer.stop();\n```\n\nYou can also create an once timer.\n\n```\nconst timer = new Timer(1000, { once: true }); // after 1000ms\ntimer.addEventListener('tick', () =\u003e console.log('Hi');\ntimer.start();\n```\n\n### Stack and Queue\n\nStack is LIFO(Last In First Out) and Queue is FIFO(First In First Out).\n\n```\nconst stack = new Stack();\nstack.push(1);\nstack.push(2);\nconsole.log(stack.pop()); // 2\n\nconst queue = new Queue();\nqueue.enqueue(1);\nqueue.enqueue(2);\nconsole.log(queue.dequeue()); // 1\n```","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkotofurumiya%2Fomnikit","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkotofurumiya%2Fomnikit","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkotofurumiya%2Fomnikit/lists"}
