Align or distribute artboards to each other

Anyone else interested in this I found this script from Paul Riggott really helpful too.

Space layers

PS-Scripts/Space Layers.jsx at master · Paul-Riggott/PS-Scripts · GitHub

Exact same functionality as distribute spacing in inDesign. Allows vertical and horizontal distributed spacing between layers or artboards.

Pasted below for reference:
