You know what’s worse than meetups without a conference…? A conference without meetups!

Dear JavaScripters,

Our very first and very real full-day conference was amazeballs ( and all of us are proud like a 🦁. Make sure to check out the official after-movie (

Does that mean we no longer care about meetups, you might wonder? Hack no! At then end of the day there is nothing that we love more than a sweet night with friends, so we can’t wait for the new season to rear its geeky head.

Our welcoming and accessible events would not be possible without the support of our our partners. Huge shout out to this edition’s main partner: Bluefront (

If you think your company can support us, please check the sponsorship packages ( and mail us ([masked])!

Peter-Paul Koch (

As a prominent member of the first generation of web developers, ppk has had a lasting impact on the course of the web as a programming platform. Many people will simply know him as the author of QuirksMode (, which has long served as a de-facto reference guide for anyone taking up the web on its cross-platform promise. Others may identify him as one of the founding fathers of the Fronteers ( association and conference.

In an intimate fireside chat he will share with us his experiences of life as a web developer now versus then.

Federico Pereiro

Over the last year Federico has been writing an open source frontend framework from scratch. In his talk, he will explain some of the reasons behind embarking on this crazy endeavour. He will elaborate on the fundamentals chosen to build the framework upon. Last but not least, he will show us some of the implementation details under the hood. Tag along with Federico and experience the ups and downs of his creative process!

Federico is a full-stack JavaScript developer, originally hailing from Argentina but nowadays an aspiring Leidenaar. He is unduly obsessed with counting lines of code.

Elena Vilchik ( & Carlo Bottiglieri (

How to use SonarJS fro bug prevention in a development team and how does it work? After a quick demo, Elena & Carlo will look into what it means to build a code analyzer and how the code is represented at different levels of abstraction. They will show live usage examples and how code analysis fits into a development team’s toolchain.

Elena strongly believes that clean code makes a product much more robust. Since two years she contributes to SonarJS, a static analyzer for JavaScript developed by the team at SonarSource.

Currently a developer at SonarSource, Carlo has recently escaped from the corporate gilded cage. He seeks simple and expressive software design in daily work and great teams to devote to.
