I've used MermaidJS to create sequence diagrams for the project I'm working on and it helped tremendously in discovering what a heap of steaming manure I wrought.

Likewise. I also really like being able to quickly diff diagram versions to quickly see what is new since the last version.

That’s been so convenient to me, I now strongly prefer mermaidjs over more featured tools like lucid or Visio or draw.io.
