Use the XMLHttpRequest object.
There's a simple example at the top of this page:
https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest
To really understand the differences between the "networking shit" you
mentioned, you'll have to read some documentation (or at least skim their
Wikipedia entries, to get a rough overview).
In a nutshell:
* XMLHttpRequest ("AJAX"): HTTP request/response based, easy to use, your
method of choice unless you have a very good reason to choose something
else.
* WebSockets: powerful two-way communication method, can be used to
implement complex interactions between a server and a client. Once
opened, a socket stays open, allowing the server to send data to the
client without getting a request. The WebSockets only provide the
transport, you are responsible for designing the data exchange protocol.
* WebRTC: a new-ish technology optimized for audio/visual data interchange;
enables peer-to-peer connections. Use this if you want to build your own
Skype.
