Access external servers with c# or javascript

Question

how can i connect to a server or create a client in c# or javascript?

Answer 1

a client in js is nothing special you could say it's a normal website
the main difference is the server connection

you have a lot of options

one would be:
you have a server and install node.js on it, it's a free framework which let's you set up a connection to your client very easy, this one is mainly used for multilayer games, you probably heard of agar.io or slither.io they are all made with socket.io

another option would be to use a server which is programmed in php, such servers are used very very very often, if you take a look at any website with a normal login option then there is a chance of 95% (just guessing) that the server is programmed in php and contains a database

I'm not sure about c#, but I guess you programm the server in .Net or sth like that (maybe someone knows it better)
