What is a Collection object in asp using vbscript?

Question

The collection has something in common with Dictionary in VBScript, but it's not the same thing.

A collection is an object, for example, the Session.Contents property.

A dictionary is an object created using the following code.

Dim dictObj
Set dictObj = CreateObject("Scripting.Dictionary")

I want to find the differences and general information with these two types of objects in order to know how to use them.

I found these useful articles, but still do not clearly understand that the collection is really in asp using VBScript.

Using Dictionary Class in VBA

My questions:

• Is there a collection data type in VBScript? you can create a dictionary, but you cannot create a collection object.

• When a loop through a collection uses For Each, what is x, the collection key, or the value of the collection item?

  for each x in Session.Contents
  

• Why can you use the collection in this way?

  Session("FirstName")
  

  Session.Contents("FirstName")
