+Pure conjecture but I would argue that the sprawling API has made it difficult to maintain.
+
+Moreover, nhooyr/websocket has support for newer Go idioms such as context.Context and
 also uses net/http's Client and ResponseWriter directly for WebSocket handshakes.
 gorilla/websocket writes its handshakes to the underlying net.Conn which means
 it has to reinvent hooks for TLS and proxying and prevents support of HTTP/2.
 
-Another advantage of nhooyr/websocket is that it supports concurrent writers out of the box.
+Some more advantages of nhooyr/websocket are that it supports concurrent writes and makes it

+In terms of performance, there is no significant difference between the two. Will update
