This particular variation of the For Next statement is particularly helpful when iterating through arrays, objects, or collections– cases where you may not know how many items are in the object or collection with out going through them first. (Which would be a waste of resources)
 
You can use Exit For statements to exit out of a For Each Next loop, if you need to check for a condition inside the loop.

Here is an example of a For Each Next statement:

ReDim Collection(2)
Collection(0) = “Test”
Collection(1) = “Test 2″
Collection(2) = “Test 3″

For Each Item in Collection
     wscript.echo item
next
