Humans behind closures.dev
closures.dev is a friendly tour that helps you build a solid mental model of how JavaScript works — step by step, with diagrams and small experiments.
This site is made with a simple goal: to turn “I kinda memorized closures” into “I can reason about them.” If anything feels unclear, please share feedback — it directly improves the next episodes.

I’m building closures.dev to explain tricky JavaScript concepts with friendly mental models, visual diagrams, and small experiments you can run line by line — the way JavaScript would.

If you spot confusing parts, typos, or you have ideas for better explanations, I’d love your feedback. It genuinely shapes the next iteration of each episode.
