Some Closure Practice Problems For My Buddy Who Is Learning JS
Make Sure that you have Node. If you download Node then you will get npm by default which you will need.
Clone down the repository.
Run npm install in the root directory of this project
To test your solutions run npm test. This will run jest in watch mode. This allows you to not have to type npm test over and over again as jest will watch for any changes that you make.
Good Luck!
