Change:

setInterval('updateStats("updateStats")', 200);

To:

setInterval(function(){
  updateStats("updateStats");
}, 200);

Also to check if something is undefined, instead of:

if (stat==undefined)

Use:

if (typeof stat == "undefined")

Also as pointed out by @Felix Kling, you are passing stat variable via function:

updateStats(stat)

And also creating it later on inside that function:

var stat = ["online","name"];

which is weird, you should modify your code to account for that.
