HTML+CSS+JS 포트폴리오 실전 퍼블리싱(시즌1)

1번 예제 HTML <a href= " #none" class = "show-btn" > 보이기 </ a > < a href = "#none" class = "hide-btn" > 감추기 </ a > < p > 태그선택자 a를 클릭했습니다. </ p > jQuery $ ( function () { $ ( "p" ). css ({ "display" : "none" }); $ ( ".show-btn" ). click ( function () { $ ( "p" ). css ({ "display" : "block" }) }); $ ( ".hide-btn" ). click ( function () { $ ( "p" ). css ({ "display" : "none" }) }); }); 2번 예제 HTML < a href = "#none" class = "show-btn" > 보이기 </ a > < a href = "#none" class = "hide-btn" > 감추기 </ a > < div > Box </ div > jQuery $ ( function () { $ ( "div" ). css ({ "display" : "none" }); $ ( ".show-btn" ). click ( function () { $ ( "div" ). show () }); $ ( ".hide-btn" ). click ( function () { $ ( "div" ). hide () }); 1번 예제하고 2번 예제 둘다 보여주고 감추는 기능을 하는 명령문? 들 인데 2번예제의 jQuery를 1번 예제의 jQuery 처럼 작성해서 실행 시켜봤더니 동작이 안되네요?? 그 이유를 알 수 있을까요??

Slack 클론 코딩[실시간 채팅 with React]

index.tsx 파일에 const App = () => { const getName = () => { return "test";} return <div>{getName()}</div> } 예를 들어 위와 같은 구조에서 1. App 컴포넌트 내부에 getName 함수를 정의해서 사용하는거랑 App 컴포넌트 밖에 함수를 정의해서 사용하는 경우 어떤 차이가 있는지 궁금합니다 2. App 컴포넌트 내부에서 함수를 정의하는 경우 App 컴포넌트가 랜더링 될 때마다 getName 함수도 다시 만들어지는 걸로 알고 있는데 이런 일반함수들은 App 콤포넌트 밖에다 정의해도 상관이 없는건가요? 3. 상태를 변경하는 함수인 경우에만 App 콤포넌트 내부에 정의하고 그렇지 않은 경우 밖에다 정의하는게 좋을까요? 감사합니다

[리뉴얼] Node.js 교과서 - 기본부터 프로젝트 실습까지

제가 14강에서 처음 부분만 보고 readline 모듈을 사용해 node.js에서도 터미널 입력이 가능하다는 것을 알게되었습니다. 그런데 여기서 입력받는 값을 변수로 사용이 가능할까요? 파이썬에서는 아래 처럼 사용가능한 것으로 알고 있습니다. a = input("값 입력 : ") 자바스크립트로 알고리즘 공부하는것을 해보려하는데 알고리즘 공부를 할때 입력값을 자주 사용하더라구요. 그래서 readline 모듈 혹은 다른 방법으로 위에 파이썬 코드처럼 입력값을 변수로 사용할 수 있는 방법이 있다면 알려주시면 감사하겠습니다.

책에 나와있는 예제파일 활용 방법에 대해 알 수 있을까요?

미해결

[개정판] 파이썬 머신러닝 완벽 가이드

예제 코드가 나와있는 사이트에 접속은 했는데 파이썬이나 다른 어떠한 프로그램 언어도 사용해본 경험이 없어서 그런지 예제 파일을 어떻게 활용해야하고.. 강의를 통해 배운 내용을 어떻게 활용해서 공부해야 할지 감을 못 잡겠습니다.. 예제 파일이 이런식으로 나오던데 이게 뜻하는게 무엇인가요 ..? 제가 아무것도 쓰여지지 않은 백지에 예제 파일과 똑같이 작성 할 수 있을 때 까지 연습을 해야 하는걸까요?

TodoInput의 addTodo 에 헬퍼함수를 적용하고 싶다면

미해결

Vue.js 중급 강좌 - 웹앱 제작으로 배워보는 Vue.js, ES6, Vuex

저랑 같은 질문에 대한 답변이 있더라구요. 현재 구조상 어려운 것 같다고 하셨는데, 혹시 addTodo() 메서드의 로직을 store.js의 addOneTodo() 로 옮겨서 newTodoItem이나 showModal의 값을 그쪽에서 변경하도록 하는 것은 구조상 바람직하지 않은 건가요?

state 관련 질문

미해결

따라하며 배우는 노드, 리액트 시리즈 - 쇼핑몰 사이트 만들기[전체 리뉴얼]

UploadProductPage 안에 있는 FileUpload 컴포넌트에서 이미지를 업로드할 때 , image state를 UploadProductPage 에도 선언하시고 FileUpload 안에도 선언하셨는데, FileUpload 에서 image를 선언하고 props로 FileUpload 전달해 주면 굳이 2번 해주지 않아도 되지 않나요?? 혹시 이거는 재사용 때문에 설계를 이렇게 하신건지 궁금합니다.
