React is a powerful JavaScript library for building user interfaces, and a login component is essential for authentication. The core function of this component is to allow users to input their credentials and initiate a session.

```bash npx create-react-app my-login-app cd my-login-app npm start ```This establishes a boilerplate project where you can implement your login functionality.
## 3. Creating the Login ComponentNow that the environment is ready, let’s create the `Login` component.
### 3.1. File StructureCreate a folder named `components` inside the `src` directory. Inside this folder, create a file called `Login.js`. Your project structure should look like:
``` src/ └─ components/ └─ Login.js ``` ### 3.2. Basic Code StructureIn `Login.js`, begin structuring your component as follows:
