What is the advantage of using /dev/tcp/host/port

[Peng Yu]

Hi,

https://www.linuxjournal.com/content/more-using-bashs-built-devtcp-file-tcpip

I see /dev/tcp/host/port is a generic socket so that HTTP requests can
be sent to it. What is the advantage of using it instead of wget/curl?

Is it allow a connect to get established once but sent and receive
messages multiple times, whereas wget/curl has to establish a new
connection each time some messages need to be sent and received?
Thanks.
