This talk explores the journey of building quickjs.rb, a native Ruby extension for running JavaScript using QuickJS. The project began with the need to execute JavaScript within Ruby in a SaaS and involved diving into native extension development as a newcomer.

The session will cover how quickjs.rb was introduced into Ruby and Rails projects, discussing the practical outcomes, challenges faced, and insights gained. This talk aims to share perspectives on the impact and possibilities of integrating JavaScript execution into Ruby environments.
