ENJOY MARKETING-FREE CONTENT

dotJS celebrates OpenSource, which means that heavy marketing is prohibited from the theater room. Our talks are not a publicity stunt, and you're not supposed to be sold a particular technology. How refreshing!
 

However, beyond the talks, you’ll be able to engage directly with our partners at their booths. This is where marketing is allowed and business connections thrive.


Experience exclusive demos, and discover the latest JS tools and technologies that could transform how you work.

Functional Programming From Zero To Monad


Just like regular expressions and recursion, if you mention terms like monad or category theory to developers, many of them may squirm in their seats. These are techniques and concepts that more often confuse and intimidate than clarify and inspire. But this shouldn’t be so! In this workshop, we’ll build up from common and comfortable programming techniques we all know, to solid Functional Programming (FP) principles, and then to uncovering monads and other “friends” in category theory. We’ll see why monads are extremely important for our JS programs and what we’ve been missing all along!


Objectives:
1. Explore the foundational principles of FP, including minimizing side effects (pure functions), using closure to manage state, recursion, etc
2. Apply FP foundations to coding patterns, including list operations, lazy/stream processing, etc
3. Leverage FP principles with monads (and other aspects of category theory) to tackle common programming challenges, and improve coding structure


Attendees: Mid-to-senior level software developers (JS)


Pre-requisites: 36+ months of experience in JS. Attendees code along with presenter, so must have a comfortable basic dev environment (editor, browser, git).

THE URGENCY IS REAL! DON'T DELAY

With so much value packed in this event, it’s no surprise that demand for dotJS 2025 will be high. This event has always been a best-kept secret among tech insiders, but word is spreading fast. 

Act now: as prices set to rise soon, securing your spot at dotJS 2025 now is crucial. Early registration not only guarantees your place at this exclusive event but also ensures you get the best rate. 

Don’t wait until it’s too late—once we’re sold out, there won’t be another chance!

CONVINCE YOUR MANAGER WITH EASE

We know budget approvals can be a hurdle, but we’ve made it easy for you to make your case. 


Here are some compelling reasons you can present to your manager to justify the investment in your dotJS ticket:

 

  • Enhanced Productivity: The knowledge you gain will help you work smarter, not harder. You’ll return with fresh ideas and proven strategies that can be implemented immediately.

  • Innovative Leadership: By staying on the cutting edge of JS trends, you’ll position yourself (and your company) as an industry leader. This can lead to new business opportunities and a stronger competitive edge.

  • Cost-Effective Learning: Compared to other forms of professional development, dotJS offers exceptional value. The insights you gain over these two days would take months to acquire elsewhere… and at a much higher cost.

pricing F.A.Q

  • ​Can my company pay for my ticket? 

Absolutely! In fact, most of our attendees’ employers fund their tickets. It’s a small investment for the significant returns in knowledge, connections, and inspiration you’ll bring back to your company.

  • What if I can’t attend in person? 

We understand that not everyone can make it to Paris, so we offer a digital ticket option. This allows you to participate in the conference remotely, with access to live streams of all sessions and exclusive Q&As with our speakers.

  • Is the ticket price worth it? 

Without a doubt! The value you gain far exceeds the cost of the ticket. Plus, securing your spot early will lock in the lowest possible rate.
 

  • Can you then explain the price? ​​

Here is how the price for a dotJS ticket is split:

  • 25% is for the food for the full day: breakfast, lunch, multiple breaks, happy hour. We want to provide you quality food with multiple options (for vegetarians, or any other food restrictions). 

  • 20% is the location (theater). One of our main differentiators is that we aim to welcome you in the best theaters Paris has to offer, while giving you access to wifi, and ensuring it’s at the very center of Paris for easy transportation. 

  • 20% is speaker related fees: we cover transportation and lodging for speakers so that we bring you the best profiles wherever they are in the world, we also rent the theater the day before for them to rehearse in real conditions and give you the best performance the next day. 

  • 15% is live-streaming, tech and video/photo fees. A real talk is best enjoyed when a qualitative camera crew is here, and everything runs smoothly on stage.

  • 10% is goodies and staff fees.  

  • 10% is marketing and overall company expenses. 

An important part of the financement of our conferences is that we forbid any sponsoring of talks done on the main stage, which means none of our content in the theater room is supposed to sell you something. A lot of the finances come from the tickets rather than sponsors, in order to keep the content the most marketing-free possible.

  • ​I'm a freelance/student, and I can't cover my ticket. What can I do?

We get that freelance people and students don’t get the chance to have an employer that can pay for them. That’s why volunteering can be a great way to attend, give time, and experience backstage. Volunteering means you're helping the organizers before the event and during, for a limited time (eg. 3 hours), you will then have the rest of the event to enjoy for free. Leave your email on the section below to receive the volunteering program info and register.

Remember…

  • Early birds get the best rates. Don’t wait until the last minute – the earlier you book, the more you save.

  • Seats are limited. Once we’re sold out, there won’t be another chance to attend dotJS 2025.

diversity and inclusion

CHILDCARE

There will be a room dedicated to childcare inside the venue (limited to 8 children, ages between 1 and 6 years old), so that you can focus on the conference and see your child at any time during the day. 


Spots are still available, leave your email here for details and to register your child. 

VOLUNTEERS

Freelances and students can volunteer to help during the event and get a free ticket. Volunteering means you're helping a little bit before the event and during, for a limited time (eg. 3 hours), you will then have the rest of the event to enjoy for free.

  • What if I don’t print my badge before arriving at the event?
