AsyncLocalStorage + AsyncContext API

This podcast episode delves into async local storage, a JavaScript feature that enables sharing context among the call stack, and explores the recently proposed async context API. It discusses the benefits of async local storage in eliminating manual data passing, its various use cases, and its potential in simplifying request ID management and debugging. Additionally, the episode introduces AsyncLocalStorage, a tool that simplifies data management in asynchronous operations, and highlights its applications in user sessions, login, tracing, and event handling. It also addresses potential issues related to testing, memory leaks, and the need for explicit cleanup.
