In this talk, I'll dig into the process from opening and discussing an issue, to implementing a new feature on the Node.js core. I'll share how the process of fixing the child process module was, what I learned, and how you can start contributing to the Node.js core. https://2022.jsconf.kr/en/speakers/erick-wendel Erick Wendel is a professional speaker giving more than 100 tech talks in almost 10 countries around the world.

Did you know that 90% of time spent on most web pages is after page load? In this span of time, users are interacting with your website through a series of interactions such as clicks, taps, and keyboard inputs—and the slower your website is to respond to those interactions, the more likely your users will have a negative user experience with your website. At Google, we've invested significant time in creating new metrics to assess page responsiveness. One of these metrics is First Input Delay (FID), which is a load responsiveness metric that captures the input delay of the first interaction. However, we discovered that we needed a new responsiveness metric that samples more than just the first interaction—and more than simply that interaction's input delay. In order to comprehensively assess overall page responsiveness, we've created the new Interaction to Next Paint (INP) metric. INP samples all page interactions, and goes beyond measuring just the input delay. In this talk, you'll find out all about INP, how it works, why it matters, how you can measure it, and how you can improve it. https://2022.jsconf.kr/en/speakers/jeremy-wagner Jeremy Wagner is more of a writer than a web developer, but he does both anyway. He has written Responsible JavaScript for A Book Apart, as well as other publications. Jeremy will someday relocate to the remote wilderness where sand has not yet been taught to think.

Web performance and its impact on the user experience has been a huge topic over past few years. After working for over a year on a project directed towards emerging markets (namely Nigeria and Kenya), I came to realise that the popular web performance metrics are all centred around a specific type of person: someone who is used to the fast and reliable connection. In my talk I want to share my experience on how to look at the overall web performance with the new metric in mind - user’s patience. During my talk, I want to give an insight on my work with the app that is dedicated towards the users who are working with it in not-so-ideal conditions with an unreliable connection and how to guide them through this experience. I want to chat about the cases when web performance metrics as we know it will not be applicable and what can we do to ensure the user will be able to successfully navigate the app using the well designed information and some performance tricks. I will also share details about the background of users in Africa and how their perception might differ from the users we typically develop for—since these are the fastest growing markets, maybe soon this knowledge come useful to you too https://2022.jsconf.kr/en/speakers/anna-migas Anna works as a Lead UI Developer at Field Intelligence helping to bring healthcare the fastest emerging markets in the world. In her spare time she is practicing Pilates, playing Hearthstone and traveling.

English translated audio -- https://youtu.be/lCs9plDpWUo There were once browsers without element inspector, CSS without border-radius, JavaScript without arrow functions. Although a world without Flexbox and Template Literals sounds scary ... I invite you to reflect on what is really the darkest time for Front-end developers. Let's ask ourselves if the times were dark when we were worried about border-radius or if we should really be worried about the current times, where a simple landing needs 800kb of JavaScript to display.
