Send an array from node server to js script

Question

My server (node.js) maintains an array :

var list = [];

I want to use this array in some js code (client side). I would like to retrieve it thanks to ajax. What is the best practice?

$.ajax({
    url: "http://localhost:8000/updatePendingAlerts",
    timeout: 2000,
    success: function (data)  {
      console.log(data);
      //data should be an array

    },
    error: function(jqXHR, textStatus, errorThrown) {
      clearInterval(timeout);
      alert('error ' + textStatus + " " + errorThrown);
    }
  });

Serialise it to JSON (with JSON.stringify) and output it with an application/json content-type header.

It will then be an array in data with the client side JavaScript you already have.

thank that worked. I was just wondering if had no other options then using json. – Tristan BARDEY Apr 21 '15 at 15:58
There are lots of options. JSON is just simplest and easiest since JS speaks it natively and it maps directly onto JS data types. – Quentin Apr 21 '15 at 16:12
