[React] 당신은 상태를 필요로 하지 않을 것입니다. #4 - 비동기(with. use) 편

이 포스트는 React 버전 18.3.1을 기준으로 합니다. 이번 편은 이전 편으로부터 이어집니다. use의 구체적인 동작은 다음과 같습니다. use는 호출자로부터 Promise를 전달받습니다. Promise가 추적 중인지 확인합니다. 추적 중이 아니라면 추적을 시작합니다. 추적 중인 Promise의 상태를 확인합니다. 상태에 따라 다음을 진행합니다. 진행(pending) - 대기 Promise 객체를 throw 합니다. Suspens...

[React] 당신은 상태를 필요로 하지 않을 것입니다. #3 - 비동기(with. Suspense) 편

이 포스트는 React 버전 18.3.1을 기준으로 합니다. 파생 상태의 유형이 Promise인 경우엔 어떻게 해야 할까요? 안타깝게도 클라이언트 측에서는 비동기 컴포넌트가 지원되지 않습니다. 따라서 useState와 useEffect를 함께 사용하여 이를 해결해 왔습니다. 하지만 Suspense의 등장으로 이를 해결할 수 있게 되었습니다. <Suspense fallback={<div>로드 중...</div>}> <Fulfilled p...

Asynchronous Programing

Asynchronous Programming allows to perform tasks that takes time to execute (such as fetching data from a server or reading files) without blocking the execution of other code. Instead of waiting for a task to complete, the code moves on to other tas...

Mastering JavaScript: From Sync to Async and Beyond

How JS executes the code? JavaScript execution involves two main stages: creation and execution. These stages are managed within special environments called execution contexts. 1. Creation Phase (Setting Up the Stage) Global Execution Context (GEC):...

关于 Promise 的重试

这段时间经常用到重试功能，因为一些需求实现起来需要频繁访问接口，但这个接口不是我们自己的，服务器在海外，所以访问起来失败率肉眼可见地高，所以我需要在访问失败（因为连接原因）时自动进行重试。既然常用，那就把他记下来，方便下次查阅。实现先准备一个假的 fetch，在文章里面我不会真去访问这个接口，就拿假 fetch 来当例子： const fetch = (url) => { return new Promise((resolve, reject) => { const r = M...

Promise 객체

Promise 객체 프로미스 객체의 필요성 프로미스 객체에 대해 이야기 하기전에 자바스크립트의 비동기 처리에 대해 다시 한 번 살펴보자. 앞서 setTimeout함수를 이용해 작업을 비동기적으로 처리했었고, setTimeout함수는 작성된 코드와 같이 콜백함수와 ms단위의 지연 시간을 매개변수로 입력받는 함수라고 배웠었다. 아래는 지난시간 작성했던 workA, workB, workC 함수를 비동기 함수로 다시 생성하고, workD는 동기적으로 ...
