Deallocating memory in VB Script

I came across a few articles which talk about setting objects to 'Nothing' after its usages to release memory though I did not find any specific pointer about normal variables.

I variable should be set to 'Empty' to deallocate memory, i.e.

******************************
Dim aVariable
aVariable = 1
aVariable = Empty

MsgBox IsEmpty(aVariable)

Dim aObject
Set aObject = CreateObject("Scripting.FileSystemObject")
Set aObject = Nothing

MsgBox aObject Is Nothing
******************************

Return only first or last element from webelements collection

Note: If you are new to java and selenium then start with selenium java training videos .

For example on a search result page we may like to click on only first and last link and not all. This is when Iterables API comes handy. (By the way I am assuming that you have already completed watching selenium training videos :)). Once we have collection of web element then we can use Iterables to get only first or last element as following - Consider that we fetch collection of element as - List< WebElement > webElements = getDriver().findElements(By. id ( "htmlID" )); Now we can get the first web element from this collection as - WebElement firstElement = Iterables. getFirst (webElements, getDriver().findElement(By. id ( "defaultElement" ))); Herein second
