jQuery ajax scope memory leak

Question

I wonder whether memory leak can occur in the following pseudo jQuery code (because the success callback always have a reference to _this)?

var _this = this;

$.ajax({
  url: "foo",
  type: "POST",
  data: data,
  success: function() {
      // Do stuff with _this
      _this.doStuffs();
})

Answer 1

Is this code within a function ?

If yes (which I guess), _this will be illegible to garbage-collection right after the ajax call has completed or failed. So there is no reason in theory to worry about memory leak here.
