@js-sdsl/priority-queue

A javascript standard data structure library which benchmark against C++ STL

English | 简体中文

✨ Included data structures

- Stack - first in last out stack.
- Queue - first in first out queue.
- PriorityQueue - heap-implemented priority queue.
- Vector - protected array, cannot to operate properties like length directly.
- LinkList - linked list of non-contiguous memory addresses.
- Deque - double-ended-queue, O(1) time complexity to unshift or getting elements by index.
- OrderedSet - sorted set which implemented by red black tree.
- OrderedMap - sorted map which implemented by red black tree.
- HashSet - refer to the polyfill of ES6 Set.
- HashMap - refer to the polyfill of ES6 Map.

⚔️ Benchmark

We are benchmarking against other popular data structure libraries. In some ways we're better than the best library. See benchmark.

$3

`html


`

$3

`javascript
// esModule
import { OrderedMap } from 'js-sdsl';
// commonJs
const { OrderedMap } = require('js-sdsl');
const myOrderedMap = new OrderedMap();
myOrderedMap.setElement(1, 2);
console.log(myOrderedMap.getElementByKey(1)); // 2
`

🛠 Test

$3

We use karma and mocha frame to do unit tests and synchronize to coveralls. You can run yarn test:unit command to reproduce it.

$3

We tested most of the functions for efficiency. You can go to gh-pages/performance.md to see our running results or reproduce it with yarn test:performance command.

You can also visit here to get the result.

⌨️ Development

Use Gitpod, a free online dev environment for GitHub.

![Open in Gippod](https://gitpod.io/#https://github.com/js-sdsl/js-sdsl)

Or clone locally:

`bash
$ git clone https://github.com/js-sdsl/js-sdsl.git
$ cd js-sdsl
$ npm install
$ npm run dev # development mode
`

Then you can see the output in dist/cjs` folder.
