Few months ago we have introduced Quokka.js — Live Scratchpad for JavaScript in your editor, with access to your project’s files, inline reporting, code coverage, rich output formatting, automatic node packages installing, and much more.

Since then the tool had been downloaded around 200,000 times (for VS Code and JetBrains IDEs) and the number of active users is quickly growing. We are very excited to see people doing more interesting things (in addition to what we have already shared) with the help of Quokka.js, such as acing technical interviews and producing the awesome JavaScript show while using the tool to demonstrate async/await concepts.

Today I am happy to share one more reason to try Quokka, if you still haven’t — we have released Atom editor integration! We know many of you had been asking for it, so we are finally happy to announce it.
