I tried to post a question regarding After Effects expressions in the Graphic Design forum - that was flagged as off topic. I am aware that code scares many designers away, but in my experience, expressions are written in After Effects to achieve visual effects that are likely not possible by using keyframe-based animation alone. How an expression is coded is very much a design decision.
I tagged the question with "adobe-after-effects" but was surprised that there was no expressions related tag. Am I truly off topic with the subject of my question? I'd appreciate hearing any opinions. Thanks!
