I keep reading that under render there is a JavaScript Console I can use.  Can someone help point me in the right direction.  What I am trying to achieve is to write a JavaScript that changes all the object descirption attributes to a specific text of information.

Is this a console in the Inkstitch extension ? 

Or something else ? 

Inkscape itself does not have a javascript console.

It has a mostly python extension system.

The closest to a python console is the excellent "simple python scripting" by Scott Pakin - https://inkscape.org/~pakin/★simple-inkscape-scripting
