How to use this repository
Install all dependencies

$ npm install

Run ESLint: You may want to run it to check code quality.

$ npm run lint

Run all tests

$ npm test

Run tests by name

$ npm test -- 'LinkedList'

Troubleshooting: In case if linting or testing is failing try to delete the node_modules folder and re-install npm packages:

$ rm -rf ./node_modules
$ npm i

Playground

You may play with data-structures and algorithms in ./src/playground/playground.js file and write tests for it in ./src/playground/__test__/playground.test.js.

Then just simply run the following command to test if your playground code works as expected:

$ npm test -- 'playground'
