What Hacker News says
7 sourcessurprised to not see anyone mention https://shadertoy.com
also check out bonzomatic:

You can find some live bonzomatic shader coding vids on youtube too, it's even done competitively at demo parties these days:

In Creative coding, making loops with ProcessingFast iteration can be achieved with compiled game logic as well, it all comes down to how things are factored in your project.
An excellent example most with OpenGL experience may be familiar with is supporting hot reloading of GLSL for fast vfx development iteration. It's a compiled language, it gets compiled at runtime without significant delay, and most of us making games have created simple tools to support live editing of GLSL, maybe even supporting it in-game for dev builds.
The demoscene has even turned it into a form of competitive performance art:
https://github.com/Gargaj/Bonzomatic
Edit:
Forgot to mention Casey also goes through support of hot-reloading game logic using C in the Handmade Hero series on YouTube.
In Parsing S-expressions in C (2019)Presumably they mean something like https://shadertoy.com but native, like the demo scene's Bonzomatic.
