Adobe Illustrator Scripting

Hey All,
Been a while since I posted on here, but I’ve been tasked with scripting out some changes in Adobe Illustrator and had a general question. Does anyone know any previous forum discussions, links, hidden gems of insight on adobe Illustrator scripting, etc that may point in the right direction to script out some color changes to .ai files? I’ll eventually have to batch through a few hundred files once I have figured out how to script out the proper changes.

Just looking for any links, general direction, etc.

Thanks! - Trey

Main Doc I found: http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/illustrator/sdk/CC2015_3/Illustrator%20JavaScript%20Scripting%20Reference.pdf
Additionally found this site: http://yearbook.github.io/esdocs/#/Illustrator/Transformation

The following is the final script (A version of it) I used for this task. Hopefully it will help others.
What it does: I needed to change a stack of AI files, which contained a green fill color (3 different slight variations in each, due to 3 different designers.). They needed a blue fill color (Specified within the script). Additionally I needed to save out a new AI file with a _blue at the end to denote it is the blue version, as well as export out a new png file of the blue map. The script also unlocks, locked layers in order to do this. After each file is processed, it is closed, and it moves to the next file in the queue. Any other questions ask and I will be happy to clarify. - Trey
