Changes between Version 1 and Version 2 of Ticket #10050, comment 4

v1	v2
3	3	A few general things to look out for are:
4	4	* Clean up any jquery data cache you may be using. It is good practice to accompany any calls to {{{.data('x',y)}}} with a {{{.removeData('x')}}}
5		* In general avoid using references to DOM elements in anonymous functions which are defined outside the scope of that anonymous function. Re-select unless you are sure the anonymous function will be made eligible for GC. For example if the anonymous function is used to register for an {{{.on('click', ...)}}} then you want to make sure you do an {{{.off('click', ...)}}}
	5	* In general avoid using references to DOM elements in anonymous functions which are defined outside the scope of that anonymous function. Re-select unless you are sure the anonymous function will be made eligible for GC. For example if the anonymous function is used to register for an {{{.on('click', ...)}}} then you want to make sure you do an {{{.off('click', ...)}}} or equivalent call to un-register the event so there is no longer a reference to the anonymous function
6	6	* Avoid storing references to DOM elements in the {{{data}}} cache, or if you must make sure that you clean up after yourself. (inspect line 539 {{{return this._renderItem( ul, item ).data( "ui-autocomplete-item", item );}}})
