QUESTION
I am trying to find a way to build a function that takes in a state, only allows specifying a property name based on a type (in this case string
) and then doing something with that property.
In the following case everything works well except within the body of the function. The line return prop.substr(0) + payload

Your server-side route (if you even have one) for
script(src='node_modules/jquery/dist/jquery.min.js')
is not working so jQuery never loads in the web page. Thus, no attempt to use jQuery works.Your socket.io server is not started or initialized properly on the server.
To be able to suggest fixes, we'd need to see the relevant server-side code and we'd need to know where all resources referenced in game.pug
are located in your server-side file system (full path). You are either missing route a definition for the jQuery file or there's an error in the route definition.
It does look like main2.js
is loading properly, though it immediately encounters an error because of the missing jQuery.
FYI, using script paths like this:
