Steps to locate Fonts source code (in this case the Font7x11Numeric7Seg font)

Typing 'Fonts' into the Search field at the upper right of most Espruino pages.

Noting that right clicking on almost every listed font takes one to:

Searching that list finds the desired Font7x11Numeric7Seg font.

Javascript Language Reference

The Mozilla Developer Network 'MDN' reference along with w3c.org standards are the places to go to understand the language specifics, while W3Schools has a nice interactive try before coding editor-viewer.
