What it does
Quokka.js is a rapid prototyping playground for JavaScript and TypeScript. It runs your code immediately as you type and displays various execution results in your code editor.
Quokka runs your JavaScript and TypeScript code and displays results inline in VS Code, WebStorm, and Sublime Text.
Quokka makes exploring, learning, and testing JavaScript / TypeScript blazingly fast . By default no config is required, simply open a new Quokka file and start experimenting. Focus on writing code instead of writing bespoke config files just to try a simple idea or learn a new language feature. Unlike online REPL tools and standalone playgrounds, Quokka runs your JavaScript code in VS Code, WebStorm, or Sublime , so you can avoid context switching while benefiting from your familiar editor environment and its extensions. You can also import and run files and modules from your project . Quokka 'Community' edition is free for everyone , brought to you with love by the Wallaby.js team. While…from quokkajs.com

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
