                Naming this in nested functions
              
          
    tl;dr

If you must nest functions in a way that requires access to multiple this', alias outer this to something meaningful - describe the value it's holding. Treat this as the invisible first argument.
In general though, avoiding the situation (nested functions and frivolous use of this) will frequently produce clearer results.
Naming this in nested functions

I was accidentally included in a discussion on how to best name this in nested functions in JavaScript. +1's were given to this suggestion of using _this.
Giving style advice on naming nested this without a meaningful context isn't too helpful in my opinion. Examples below have been altered to have at least some context, although a completely contrived and stupid one.

  
## swaparrayelements.js
/**
* Swap the elements in an array at indexes x and y.
*
* @param (a) The array.
* @param (x) The index of the first element to swap.
* @param (y) The index of the second element to swap.
* @return {Array} The input array with the elements swapped.
*/
var swapArrayElements = function (a, x, y) {
  if (a.length === 1) return a;

## ex1-prototype-style.js

	this.me = who;

	return "I am " + this.me;
};

function Bar(who) {
	Foo.call(this,"Bar:" + who);

    function formatCurrency(amount)
    {
      //truncate the amount to 0 decimals
      //for every digit that is followed by 3 digits and a word boundary
      //add a comma
			amount = amount.toFixed(0).replace(/(\d)(?=(\d{3})+\b)/g, "$1,");
			return amount;
