10 years of pushing the boundaries

This year we want to shift our attention to the decade of progress in the world of web development. Back in 2013, we went through a period of rethinking practices as frontend development took off and became one of the most crucial disciplines in tech. Frameworks like: React, Angular or Vue, and their ecosystems now enter into their second decade of existence, while web capabilities and standards are increasingly more potent and versatile.

So in 2023, let’s celebrate the past 10 years, reflecting on the evolution of our tools and patterns, with the good and the bad that comes with this rapid evolution.

At JSHeroes, we always ventured outside the pure language ecosystem, so expect to see a variety of talks covering the entire landscape of web development and JavaScript as a universal programming language.

But of course, we will not neglect the human side of things, in our effort to paint a full picture for the development community in 2023.

An Open-Source Community Event

We believe that the community and the open-source models are well suited for our core values: learning, teaching and knowledge sharing. Our mission is to inspire other communities with the concept of open-source events.

We’re publishing all data about this conference, in full transparency. We are also available at any time for inquires and we’re really looking forward to sharing our knowledge about organizing international events. This way, whenever a community wants to start something similar, they can build on our knowledge.
