SyntaxError: No identifiers allowed directly after numeric literal in Safari

[DelfsEngineering]

When adding the CDN and previewing my page in Safari I am seeing the following error:

SyntaxError: No identifiers allowed directly after numeric literal

This does not happen in Chrome or Firefox which leads me to think does something within the CDN need to be transpired?

Aside from that this is awesome!

FWIW, this happens in Safari 13.
