How to run the code

You will need to put the code under a HTTP server to run the code inside this folder. Opening index.html directly as a file in a browser won't work.

If you do not have a HTTP server installed, you can use the following command to install http-server, which is a simple and easy-to-use command-line HTTP server.

npm install http-server -g

Once it is installed, switch to each stage folder and run http-server and open URL http://localhost:8080 in your browser. For example, to run the stage1 code, you can do with the following steps.

$ cd stage1
$ http-server

You can specify the port number to be other than 8080. For example, with command http-server -p 3030, port 3030 will be used.
