The Project

This project consists of the following files which you can clone/download the  Github repository.

  • seven_segment_display.js
  • seven_segment_display.htm
  • seven_segment_display_page.js

The first JavaScript file contains the widget itself. The HTML file contains a set of controls to configure, control and display an instance of the widget, and the second JavaScript file contains the code for the page.

The widget is implemented as an ES6/ES2015 class. Let’s look first at its constructor.
