This is the repository for the youtube series you can find here.
You can run these applications by simply cloning this repository or downloading it via github and then starting a http server in the root directory and clicking on the application you wanna run. I use the http-server utility to do this.
You are more than welcome to hack any of the applications here and add features or improve the UI. If you have any ideas about which application I should do next, please feel free to open an issue and we can discuss more. Happy coding! :D
