안녕하세요. 사원사업부의 마루야마@h13i32maru입니다. 최근의 Web 프론트엔드의 변화는 매우 격렬해서, 조금 눈을 땐 사이에 점점 새로운 것이 나오고 있더라구요. 그런 격렬한 변화중 하나가 ES6이라는 차세대 JavaScript의 사양입니다. 이 ES6는 현재 재정중으로 집필시점에서는 Draft Rev31이 공개되어있습니다.
JavaScript는 ECMAScript(ECMA262)라는 사양을 기반으로 구현되어있습니다. 현재 모던한 Web 브라우저는 ECMAScript 5.1th Edition을 기반으로 한 JavaScript실행 엔진을 탑재하고 있습니다. 그리고 다음 버전인 ECMAScript 6th Edition이 현재 재정중으로, 약칭으로 ES6이라는 명칭이 사용되고 있습니다.
While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.
Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
