In this episode, Thomas Steiner chats with Francis McCabe from Google, who's the champion of the JavaScript Promise Integration and the Stack Switching proposals. They go from talking about synchronous assumptions in code over to discussing the JavaScript Promise Integration (JSPI) proposal and how to use it in practice, its performance implications, and how to use it in practice. After exploring a neat side effect of JSPI, namely lazy loading, the fall into the rabbit hole of comparing JSPI to the upcoming ES module integration of Wasm. Finally, Francis gives an overview of his other early stage Stack Switching proposal.
