You can find all the code to create this component on this page, however you can also consume it as a web component. JB explains this on his github account as well, you can see how the development effort will go down, mixing different JET components. After installing, when consuming the web component for the memory game, this is all the HTML code needed to embed on your webpage:
- The Oracle JET page
- Web Components
- JB’s github
- CCA : Composite Component Architecture
