@ponderingdemocritus Hello 👋 I have implemented latest rc1 in React, is that OK If get this one assigned? should I mimic what was made here? https://github.com/dojoengine/dojo.js/tree/main/examples/example-vite-react-sdk

Here the idea @RolandoDrRobot is to have a pure JS approach, and it should be with 1+ version, would that be ok @RolandoDrRobot?
