Lynx.js introduces a dual-threaded approach that separates UI responsibilities from background work. This model opens the door for smoother interactions, predictable performance, and a clearer mental model for how logic flows through an application. This week, Łukasz Chludziński and Kewin Wereszczyński will walk through how this structure works in practice.

The session will explain the two-thread design used in Lynx.js: how the main thread and background thread communicate, what developers gain from this division, and how it differs from the traditional React Native execution model.

From there, Łukasz and Kewin will explore the APIs that let developers move work between threads, including guidance on deciding which operations belong where and examples of how the runtime handles transitions. They will also do some live coding focused on the dual-threaded model working inside a real application. This includes a direct comparison to React Native, making it easier to understand where Lynx.js aligns with familiar patterns and where it opens up new possibilities for structuring logic.
