Happy to be back ♥
After 41 editions of dotConferences since 2012, with more than 24,000 attendees and a forced 4-year break, dotConferences made their comeback in June 2024 starting with dotJS.
During most dotJS editions, we welcomed 1500+ attendees per day! We can’t wait to welcome you on September 18, just after dotAI (Sept 17), to get the latest news, features and best practices about JavaScript. Let’s meet together to pursue the fantastic dotJS conference atmosphere!
