The general pattern for doing updates on persisted JSON documents in JavaScript
is to
1) get the document
2) turn it into an object
3) update the object
4) replace the document node with the updated object
Here's an example that updates the `balance` property of every document in the
`accounts` collection:
declareUpdate();
for(var doc of fn.collection('accounts')) {
var account = doc.toObject();
account.balance = account.balance * 1.05;
xdmp.nodeReplace(doc, account);
}
Note that you also need a declareUpdate(). The transaction is committed (or
rolledback) automatically, so you don't need the xdmp.commit().
