# React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh

## Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

- Configure the top-level `parserOptions` property like this:

```js
export default tseslint.config({
languageOptions: {
// other options...
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
},
})
```

- Replace `tseslint.configs.recommended` to `tseslint.configs.recommendedTypeChecked` or `tseslint.configs.strictTypeChecked`
- Optionally add `...tseslint.configs.stylisticTypeChecked`
- Install [eslint-plugin-react](https://github.com/jsx-eslint/eslint-plugin-react) and update the config:

```js
// eslint.config.js
import react from 'eslint-plugin-react'

export default tseslint.config({
// Set the react version
settings: { react: { version: '18.3' } },
plugins: {
// Add the react plugin
react,
},
rules: {
// other rules...
// Enable its recommended rules
...react.configs.recommended.rules,
...react.configs['jsx-runtime'].rules,
},
})
```

할 일 개수를 관리하는 이 count 상태가 꼭 필요한지 생각해보세요!

const[count, setCount] = useState<number>(0);

이렇게 타입과 초기값을 명확히 추가하시는게 좋아요!

const [inputValue, setInputValue] = useState("");

const [itemList, setItemList] = useState([] as TodoList[]);

const InputChange = (event: React.ChangeEvent<HTMLInputElement>) => {
setInputValue(event.target.value);
};

이 부분에서 event: 는 e로 축약해서 적을 수 있어요!


const AddItem = () => {
if (inputValue.trim()) {
const newItem: TodoList = {
id: itemList.length + 1,
todoText: inputValue,
isDone: false,
};
setItemList([...itemList, newItem]);

filter(_, idx) 부분에서 _ 이건 무엇을 의미하나요?


const BoxChecked = (id: number) => {
const updatedList = itemList.map((item, idx) => {
if (idx === id) {
item.isDone = !item.isDone;
}
return item;
});

setItemList(updatedList);

if (updatedList[id].isDone) {
setCount(count - 1);
} else {
setCount(count + 1);
