I didn't know what SSE was, so I asked ChatGPT:

> What does 'SSE' stand for in the following code sample: <pasted fetch-sse.js>

"In this code sample, 'SSE' likely stands for "Server-Sent Events". It is the name of the fetchSSE function and it is used to fetch data from a server using the Server-Sent Events protocol. This protocol allows a server to push data to a client in real-time, rather than requiring the client to continually poll the server for updates."

Not sure how accurate this is but it gave me enough information to look into it more!
