Question: Should we use JS or use TypeScript?

Question: Should we use JS or use TypeScript?

All should move to TS soon :) This is an adapted version of the logic in the depths of playground at https://github.com/eclipse-thingweb/playground/blob/master/packages/core/index.js#L1305

Since the code in detectProtocolSchemes.js isn't really complex we could do it right away... Anyway it is fine by me.

I'm on it now

We had some discussion on this in the regular call:

1. The test file should contain the expected output and not the TD
2. The expected output should look like the following:

   "protocolSchemes": {
     "http":[{
       "uri":"http://mylamp.example.com:8080",
       "subprotocol":"longpoll"
     },
     {
       "uri":"http://mylamp.example.com:8081"
     }]
