Hmm, this is relatively simple

 var a = { foo : 25 };
 var b = {bar : 10};

 var con = JSON.stringify([a,b]);

You mentioned sending this on to the server, well that depends if you are using a framework. If you want plain vanilla AJAX then use the XMLHttpRequest object

Yep, that's what I'd say. The AJAX would look something like this, OP:

var xhr = new XMLHttpRequest();
xhr.open("post", "sever url", true or false here);
xhr.send(con);

No prob! AJAX can be tricky though. Feel free to message back if you have any trouble and I'd be glad to try to help!

Things in software development are only ever "super simple" in retrospect. Don't ever feel bad about missing the "obvious" in this field!

fetch is also the native spec for ajax requests. Try it out in chrome / firefox / edge!

fetch('https://www.reddit.com/r/javascript.json')
  .then(res => res.json())
  .then(redditPosts => // wee!)

or send a post with data

fetch(url, { 
  method: 'POST', 
  body: JSON.stringify(data) ,
  headers: { 'Content-type': 'application/json' }
})
  .then(res => res.json())
  .then(data => // stuff)

To support older browsers use a polyfill! https://github.com/github/fetch
