오늘은 React 개발자가 꼭 알아야 할 핵심 개념들을 알아보겠습니다.1. Component가 뭔가요? 🧩레고 블록을 생각해보세요!레고처럼 작은 부품들을 조립해서 큰 작품을 만드는 것UI를 재사용 가능한 조각으로 나누는 것이 바로 Component예요// 함수형 컴포넌트 예시function Button({ text, onClick }) { return ( {text} );}// 사용 예시 alert('안녕!')} />2. Props와 State 🎭Props (Properties)마치 택배 배송처럼 작동합니다!부모가 자식에게 전달하는 데이터읽기 전용 (수정 불가)컴포넌트의 "설정값"// 부모 컴포넌트function Parent() { return ;}// 자식 컴포넌트fun..

React Hooks는 함수형 컴포넌트에서 상태 관리와 생명주기 메서드를 사용할 수 있게 해주는 기능입니다. React 16.8에서 도입되었으며, 클래스 컴포넌트 없이도 React의 다양한 기능을 활용할 수 있게 해줍니다. 주요 훅으로는 useState, useEffect, useContext, useMemo, useCallback이 있으며, 개발자가 직접 커스텀 훅을 만들어 컴포넌트 로직을 재사용할 수도 있습니다.오늘은 React 개발을 더 쉽고 효율적으로 만들어주는 React Hooks에 대해 알아보겠습니다!React Hooks가 뭔가요? 🤔여러분의 집에 다양한 스마트 기기들이 있다고 상상해보세요.스마트 메모장은 중요한 정보를 기억합니다스마트 비서는 특정 이벤트가 발생할 때 작업을 수행합니다스마트 ..

The virtual DOM improves performance by minimizing direct updates to the real DOM, making updates more efficient and reducing the computational load on the browser.The Big PictureImagine you are organizing a large stack of papers. If you had to update each piece of paper individually, it would be time-consuming and tedious. Instead, you create a checklist of changes to make and then apply all ch..

In this response, I'll guide you through creating a simple React component that displays a message passed as a prop, breaking down each step with an analogy to make the process clear and understandable.The Big PictureImagine you're building a small sign that can display different messages. The message on the sign can be changed by providing a new message. In React, we create components to build ..

The React component lifecycle consists of a series of methods that are invoked at different stages of a component's existence, allowing you to control its behavior from creation to destruction.The Big PictureImagine you’re organizing a stage play. The lifecycle of the play involves various stages: setup (mounting), running the play (updating), and teardown (unmounting). Each stage has specific t..

React components are special JavaScript functions or classes that return JSX to define the structure and behavior of a user interface, whereas regular JavaScript functions do not inherently have this UI-focused capability.The Big PictureThink of a React component as a self-contained, reusable building block for a web application, much like a LEGO piece that can be used to build complex structure..

JSX is a syntax extension for JavaScript that looks similar to XML or HTML and is used in React to describe the UI structure in a declarative way.The Big PictureImagine you are describing the layout of a house. Traditional JavaScript lets you describe each element individually, like writing a list of instructions for a builder. JSX, on the other hand, allows you to draw a blueprint where you can..

React is a JavaScript library for building user interfaces, especially for single-page applications where data changes over time.The Big PictureImagine building a complex structure with Lego blocks. Each block can be customized, and you can piece them together to form various structures. In the world of web development, React allows you to create user interfaces in a similar modular way, where e..
