Maxim Salnikov delivered the talk "Service Worker: taking the best from the past experience for the bright future of PWAs" at the conference Codemotion Milan 2018. We interviewed Maxim asking him these questions: What programming language would you recommend to someone who is interested in frontend? What do you like the most, being a conference organizer or a community leader? What are the properties/benefits of Progressive Web App and Service Workers? What are the best practices to effectively develop PWA and SW? What are the main challenges of moving from a "traditional" web app to a progressive one? Service workers are a fresh technology, and are fully supported only on recent browser: how can developers be more inclusive to end users with old technologies?
