Hyperconnect 장소 대관을 위해 이번 밋업에 대해 소개서를 작성해보았습니다. Blockchain Korea Summit은 소/중 규모 블록체인 모임입니다. 초보자 분들도 모두 모여 삼삼오오 블록체인에 관해 배우고 정보를 공유하는 밋업을 주최하는 것이 목표입니다. 입장료 또한 무료로 생각하고 있습니다.
I'd like to begin this article by sharing my frustration with a pool of misleading and often "this is how it just works" articles floating around the internet. I'm tired of seeing myself getting tired after having read through the first 10 pages of the Google search.
I've conducted over 1000+ survey results from the iOS developers and students. RxSwift has been brought up often times. Yet, most of them tend not to use this framework for there is a steep learning curve.
Now I see why. There aren't many people who can explain the concept using analogy and stories. You've come to the right place. I've decided to get my hands dirty with RxSwift and contribute to this phenomenal community.
