Hi HN, we’re Matt and Mayank of Roundtable. We’re launching RoundtableJS, an open-source library (https://github.com/roundtableAI/roundtable-js) to program research surveys at scale. Academic and market researchers want a DIY platform for survey research. Most existing tools are no-code, and these researchers want programmatic software that handles advanced branching logic and customization. We know this because we spent five years using open-source survey software for our academic work. One of the key insights of RoundtableJS is to leverage JavaScript’s async/await…

Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate. Such a nice DX combo for writing new languages. Still a work in progress, but I thought I'd share :)

Hi all, I've made a javascript library to simplify searching/sorting/filtering in arrays of objects. Its inspired by both GraphQL and SQL, but implemented using javascript Proxies. Instead of creating a new language, its all just javascript. I've made it as part of an experimental database, which uses javascript as the query engine. The normal javascript map/reduce/sort functions are quite difficult to master for junior developers. JAQT is easier to explain, and can still be used in combination with any existing array functions. Please let me know what you think of the…

I started writing this book 10 years ago in JavaScript, got through a few chapters (asymptotic notation, basic techniques, start of sorting), and then abandoned it. Recently I picked it back up, converted everything to TypeScript, and used AI (Zenflow [1] + Claude Opus 4.6) to complete the remaining chapters. I provided the structure, direction, and initial chapters; the AI generated the bulk of the remaining content under a spec-driven workflow. The book covers roughly a first 1-2 year CS curriculum: sorting, dynamic programming, graph algorithms, trees, heaps, hash tables, and more. All…
