+## TypeScript
+Normally you can use compile the TS file to JS using the tsc compiler. But for ease in this simple scripts i suggest installing: `npm install -g typescript ts-node`. With this you can just run the TS file at once and get the output without compiling and running over and over.

 ## Feedback and Collaboration
 I'm always open to feedback and suggestions for improving the solutions.
