Notes on automating macOS using Javascript (JXA)

Original goal:

• open a web page and automate the process of selecting "export to PDF..." from that page.

Resources that helped significantly:

VisionOS notes


Q: Curious what tools or workflows designers are using to mock up things like volumes or immersive spaces considering things like Sketch and Figma are 2D or "window" based?

A: Great question! We find a lot of people start with our visionOS Apple Design Resources especially on Figma (https://www.figma.com/community/file/1253443272911187215) and animate flat views to sell the ideas to partners. Then we've seen folks move to tools like Spline (https://spline.design), Blender, etc. for 3D workflows. In particular, Spline has a visionOS mirror app (https://docs.spline.design/doc/spline-mirror-for-visionos/docaQJC8SwTF) that makes it much more efficient to prototype 3d environments! 

Q:  I'm generating mesh data in code and then programmatically creating objects in a volume. As the app progresses, I need to switch out some of those meshes. If this is happening fairly rapidly (multiple times per second), would it generally be better to keep a reference to the entity to be able to update it, or sho
