Translate a short python program to javascript

I need a short python program converted to javascript and embedded in a simple page (React or possibly something else) with some controls for the variables in the script as well as a window that displays the output. The program should also have a button to generate the next image instead of it being done automatically as well as a button to save the generated image to file. If bidding please let me know what you would embed the javascript code in e.g. HTML, React, etc.
