Episode notes

Server-sent events are ideal for scenarios where the server needs to send updates to the client regarding the progress of long-running processes, such as video processing or AI generation. This method is effective for one-way communication from the server to the client, as it informs the client of the status at intervals. In contrast, WebSockets are better suited for applications that require real-time bidirectional communication, such as chat applications, where both the client and server need to exchange messages instantly.

Scott and Wes serve up a gameshow-style quiz with STUMP’d, challenging each other on web development trivia. From the differences between useMemo and useCallback to the intricacies of the JavaScript event loop, join them for a fun and informative session packed with web dev insights!
