### ⚠️ Warnings (1)

**`no-react-dom-deprecated-apis`**

ReactDOM.render is the legacy root API — switch to `import { createRoot } from 'react-dom/client'` and call `createRoot(container).render(...)` (REMOVED in React 19)

> Switch the legacy `react-dom` root API (`render` / `hydrate` / `unmountComponentAtNode`) to `createRoot` / `hydrateRoot` / `root.unmount()` from `react-dom/client`. Replace `findDOMNode` with a ref. The whole `react-dom/test-utils` entry point is removed in React 19 — use `act` from `react` and `fireEvent` / `render` from `@testing-library/react`. Only enabled on projects detected as React 18+.

[`src/index.js:9`](https://github.com/celeroncoder/Trello-Clone/blob/08da7d8bbf949f3274437df484ffbf694e2441bc/src/index.js#L9)
