Day 5/90: Control flow
90 Day JavaScript Challenge: Zero to Production
Today I wanted control flow to feel like a real engineering decision, not a syntax demo. The useful shift was using control flow to keep workflow rules separate from framework and storage details.
The checks that mattered were domain boundaries, dependencies that point the right way, and failure paths designed as early as the happy path.
The failure mode I was actively trying to avoid was spreading workflow rules across modules without a clear ownership model. I wanted control flow to feel like something I could explain at a whiteboard or in a code review, not just something I recognized from docs.
That is the bar I want from this track: code that stays readable when requirements move, not just code that compiles today. I also want to keep tracing one concrete path through the code because that exposes weak assumptions faster than a larger demo.
