NamasteJS

What it does

NamasteJS visualizes JavaScript's invisible runtime. Watch closures form with memory addresses, see the event loop animate in real-time, and understand hoisting through step-by-step execution. Unlike docs that explain or playgrounds that show output—we show the journey. Control speed, pause mid-execution, and finally understand concepts that appear in every interview. Free, open-source, no signup. Stop reading about JavaScript. Start watching it run.

Practice JavaScript interviews with AI interviewers. Master closures, async/await, React, Node.js and land your dream job with unlimited AI-powered mock interviews. Free to start!

  LiveViewJS – TypeScript back end for LiveView Apps (Phoenix LiveView)2022 · github.com · ▲146

  Author here. I really love the programming paradigm behind by Phoenix LiveView applications and wanted to expand the ecosystem to include programmers like myself that love Typescript. In summary, LiveViewJS reuses all the Phoenix client code and implemented a new backend in Typescript to handle client events and send back updates. Lots more detail and examples in the repo. Would love any questions and/or feedback. Thanks!

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
