I have a Dictionary object in VBScript. How can I copy all the objects contained in it to a new Dictionary, i.e. create a clone/duplicate of the dictionary?

to add the div. Then we can clone the div by writing: const div = document. getElementById('foo') const clone = div.
Use copy() This is a built-in Python function that can be used to create a shallow copy of a dictionary. This function takes no arguments and returns a shallow copy of the dictionary. When a change is made to the shallow copy, the original dictionary will remain unchanged.
By using dict. copy() method we can copies the key-value in a original dictionary to another new dictionary and it will return a shallow copy of the given dictionary and it also helps the user to copy each and every element from the original dictionary.
deepcopy() To make a deep copy, use the deepcopy() function of the copy module. In a deep copy, copies are inserted instead of references to objects, so changing one does not change the other. The following is an example of applying the deepcopy() function to a slice.
Create a new Dictionary object, iterate through the keys in the original dictionary and adds these keys and the corresponding values to the new dictionary, like this:
Function CloneDictionary(Dict)
Dim newDict
Set newDict = CreateObject("Scripting.Dictionary")
For Each key in Dict.Keys
newDict.Add key, Dict(key)
Next
newDict.CompareMode = Dict.CompareMode
Set CloneDictionary = newDict
End Function
This should be enough in most cases. However, if your original dictionary holds objects, you'll have to implement deep cloning, that is, clone these objects as well.
