I have a collection in Firestore with the following structure:

Publications 
 PubData <---- This is a Doc
 1892872 <---- This is a map 
 Name: abc
 Id: 123 
 1892875 <---- This is a map 
 Name: abc
 Id: 123 

Querying the PubData document:

fb.publicationsCollection
 .doc("pubdata")
 .get()
 .then(res => 
 let pubData = res.data();
 )

returns the following data:

1892872: …, 1892875: …

How can I return this as an array, so I can iterate over it with a for loop?

You can iterate an object's properties with a foreach loop:

const pubData = res.data();
Object.keys(pubData).forEach(function(key) 
 // key is 1892872, pubData[key] is the associated object
 console.log(key, pubData[key]);
);

Since you didn't really say what exactly you wanted the array to contain, I'll leave it up to you to figure out how the keys and values of the document's map should be represented in that final array.

 let pubData = Object.entries(res.data());
 // pubData will look like:
