The panel discussion titled "Modern JS" features speakers Dawid Pośliński and Maciej Walusiak at the wroc_love.rb 2018 conference, focusing on the evolution and future of JavaScript development. The conversation starts with a provocative comparison of old libraries like jQuery and Prototype, suggesting that modern JavaScript no longer requires these tools due to advancements in browsers and features like query selectors. Key points discussed include:

- **Redundancy of Older Libraries**: The speakers argue against the use of jQuery and Prototype, highlighting that eliminating them could potentially save build sizes significantly.

- **Emergence of CSS-in-JS**: This approach has gained acceptance, resolving many maintainability issues associated with traditional CSS. It aligns well with component-based architectures, which developers increasingly prefer.

- **Trends in Modern JavaScript**: CSS-in-JS, reactive programming (notably in frameworks like React and Ember), and conventions that streamline code maintenance are identified as persistently beneficial trends in JavaScript.

- **The Role of Node.js**: While JavaScript is essential for front-end development, the speakers note that other languages, like Ruby on Rails, may be better suited for backend roles, reflecting the diversity in technology stacks needed for different tasks.

- **Future of JavaScript**: The potential rise of WebAssembly and its implications for JavaScript applications are discussed, alongside recent TC39 proposals that could enhance language features. The speakers express curiosity about how these developments might shape the JavaScript landscape in the coming years.

- **Adaptation and Standards**: The importance of standards such as JSON API and GraphQL for API design is emphasized, along with the necessity for developers to remain adaptable when choosing technologies.

- **Innovative Tools**: The advantages of tools like Stimulus and TypeScript are acknowledged, marking them as promising for future JavaScript management.

In conclusion, the panel encourages developers to remain open-minded towards emerging technologies and standards, as being adaptive is key in the ever-evolving JavaScript ecosystem. The discussion reflects a deep understanding of both current trends and future potential in modern JavaScript development.
