How to create an Adjustment Layer in After Effects via scripting?

Question

I know it's possible to create Shape Layers and Solids via scripting, but how do I create an Adjustment Layer?

Answer 1

It's pretty simple. Every layer can be turned into an Adjustment Layer. You can simply create a solid layer and then turn it into one like this:

var solid = comp.layers.addSolid([0,0,0], 'LayerName', 1920, 1080, 1, duration);
solid.adjustmentLayer = true
