A short story about the horrors we had to face while working on someone else's code, how we managed to master ourselves and start simultaneously adding new features and slowly modernizing the old ones. About how to understand a week in four pages and why legacy is not always bad, but on the contrary — a great opportunity to pump yourself up.

A common task in modern JS is parsing, validating and then comparing JSON objects. In this talk I will quickly go through most common ways to parse/validate and compare objects we use today and then focus more on how runtime types (based on io-ts) can help make such tasks easier and quicker to implement.

Should we take a look at JavaScript when everyone is writing in TypeScript? What happens to the standard? What did we get last year? What new features can we expect this and next year? And most importantly, when will Observer be standardized? Let's try to answer all these questions and even a little more, dream about the future, and enjoy that Observer is alive (or not).

This talk aims to highlight the latest features and tools in the Node.js ecosystem. Nikita will showcase new JavaScript/TypeScript constructs, explain use cases for the new features in Node.js v20, and provide insight into the rising popularity of various frameworks and tools. However, the main focus will be on providing insightful answers to critical questions: how, when, and most importantly, why these features should be used in product development.

Workers is the open source kernel of the Cloudflare Workers platform, and despite being built around v8, and running JavaScript and WebAssembly, it is quite different from Node.js. This talk will explore the differences and similarities and hopefully give you a bit more insight into how both operate.

Let's talk about the complexity of modern frontend applications and the challenges facing contemporary development — security, performance, accessibility, and other non-functional requirements that a front-end developer must take into account while developing their application in 2023.

This talk will be about how Unit built White-Label UI Components in React while making them completely native. We will discuss rendering React in Web Components, communication with them via native JS events, and the modularity of each Component.

<p>In this talk, we will share our ways in which AI has been integrated into Wix Editor. We will showcase real-world examples of technical implementation, the challenges and obstacles that might arise during the AI integration journey, including offensive content moderation, data privacy, prompt managing, scalability and monitoring.</p>

In this talk, Roman will share his experience in researching and working with different types of artificial intelligence.
