    const myOrderedMap = new OrderedMap();
    myOrderedMap.setElement(1, 2);
    console.log(myOrderedMap.getElementByKey(1)); // 2
</script>

// esModule
import { OrderedMap } from 'js-sdsl';
// commonJs
const { OrderedMap } = require('js-sdsl');
const myOrderedMap = new OrderedMap();

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

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.

Use Gitpod, a free online dev environment for GitHub.

Or clone locally:

$ 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.
