Ghost/core/frontend/helpers/date.js
Hannah Wolfe 35e3e0708c Moved helper proxy into a service
- The proxy is not a helper, we want the helpers folder to only include helpers
- The proxy is also meant to be the interface to Ghost for the helpers, and we want to enforce that
- This is a small step on the way
