      Vector,
      Stack,
      Queue,
      LinkList,
      Deque,
      PriorityQueue,
      OrderedSet,
      OrderedMap,
      HashSet,
      HashMap
    } = sdsl;
    const myOrderedMap = new OrderedMap();
    myOrderedMap.setElement(1, 2);
    console.log(myOrderedMap.getElementByKey(1)); // 2
</script>

For npm

// 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

Build by source code

You can pull this repository and run yarn build to rebuild this library.

Test

Unit test

We use jest library to write unit tests, you can see test coverage on coveralls. You can run yarn test:unit command to reproduce it.

For performance

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.
