Your file is located in the "js" directory, and the name has a period in it, so the syntax for running it with node would be:'

node js/random.js

But, this script is intended to be run from a browser and not by using node, since it uses "prompt" which is a function found only in a browser.

So the proper way to run this would be to use the "preview" button (looks like an eye) in the upper right of the workspace window.

great Steven thank you!
