JSConf | How to Wait - Max Goodhart | JSConf Hawaii 2020 @jsconf_ | Uploaded 4 years ago | Updated 11 hours ago
Our story begins with a humble 'await fetch': your script fires off an HTTP request and settles down to nap, trusting that it'll be awoken when response data is available. While your program does nothing, a cascade of activity is now taking place: in your JS runtime, your operating system, and your hardware. What happens while your code is waiting for something to happen? In this talk, we'll peek behind the layers of the event loop, select/epoll nonblocking I/O, and hardware architecture to answer a simple question: what is waiting, and how does a program wait?

![Code Factorization: How to Organize Boilerplate Code - Jaewon Seo - JSConf Korea[Korean language]](https://i.ytimg.com/vi/Urj-aaxB6mE/hqdefault.jpg "Code Factorization: How to Organize Boilerplate Code - Jaewon Seo - JSConf Korea[Korean language]
Boilerplate code (repeatedly used pieces of code) is often the main culprit of unnecessary complexity and cognitive overload in programming. Thats why many books and experienced programmers tell us to avoid it, and we try our best by employing all kinds of methods, like inheritance and abstraction.
Despite this constant effort, we often still encounter boilerplate code. Sometimes, we run into boss boilerplate code, which we just dont know how to deal with.
This talk is for those of you whos tired of this endless battle. I will talk about code factorization, a technique that will help you gain an edge in the war against boilerplate codes. After this talk, you will be able to declare with confidence: veni, vidi, vici.")

Ryan Dahl, creator of Node.js, presented 10 Things I regret about Node.js at JSConf EU 2018 and introduced Deno, a newly developed JavaScript runtime. Four years have passed since then. What advantages does Deno have and how much ore convenient is it over Node.js? Is it okay to use Deno in production instead of Node.js now?
Through creating a Node.js project with TypeScript, we will find out the existing inconveniences and learn how Deno solves them. Also, I will introduce how to coexist with the current ecosystem based on my experience of actually using the Node.js library in Deno and deploying it to NPM. Then lets go to Deno Land together!
