Why Stauts

🤔Tell me what is the meaning of this status?

Install

npm install -g why-status

Usage

Just input ws code [lang], and you will see what is the meaning of code.

ws 101
# why-status 101

This should print some text like below:

Switching Protocols

The server understands and is willing to comply with the client's request, via the Upgrade message header field, for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response.

The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features.

Language

Currently we only support language below, it will be greate if you can give me some help.
