immutable chrome sqlite return objects

Question

I am using a sqlite DB as a storage system for a webapp. I been using the objects that are returned from queries directly in application. For example:

function g         


        

Answer 1

The WebSQL spec doesn't require for the returned item to be sealed, but it's up to the implementation (the spec does require for the item to be an ordered dictionary with the properties in the same order as the columns in your query).

And no, there is no way to explicitly request a mutable object, so you'll want to do something like the convert_to_mutable() approach suggested by Stan.

BTW, assuming you're using a 3rd party library, it probably has a function for this, for example jQuery.extend() or _.extend().
