### React Button Component with CSS Import

Source: https://github.com/packtpublishing/react-design-patterns-and-best-practices/blob/master/chapter-03/reusable-components/README.md

Demonstrates a basic React class component for a button, importing its associated CSS file using Webpack. This approach allows for component-specific styling and hot-reloading during development.

```javascript
import React, { Component } from 'react';
import './Button.css'; // Tell Webpack that Button.js uses these styles

class Button extends Component {
  render() {
    // You can use them as regular CSS styles
    return <div className="Button" />;
  }
}

```javascript
import React from 'react';
import logo from './logo.png'; // Tell Webpack this JS file uses this image

console.log(logo); // /logo.84287d09.png

function Header() {
  // Import result is the URL of your image
  return <img src={logo} alt="Logo" />;
}

export default function Header;
```

```ini
module.name_mapper='^\(.*\)\.css$' -> '<PROJECT_ROOT>/config/flow/css'
module.name_mapper='^\(.*\)\.\(jpg\|png\|gif\|eot\|otf\|svg\|ttf\|woff\|woff2\|mp4\|webm\)$' -> '<PROJECT_ROOT>/config/flow/file'
```

--------------------------------

### Referencing Images in CSS with Webpack

Source: https://github.com/packtpublishing/react-design-patterns-and-best-practices/blob/master/chapter-03/reusable-components/README.md

```css
.Logo {
  background-image: url(./logo.png);
}
```

--------------------------------

### Convert Array to Lowercase Strings in React

Source: https://github.com/packtpublishing/react-design-patterns-and-best-practices/blob/master/README.md

This JavaScript code snippet demonstrates a function that takes an array of strings as input and returns a new array with all strings converted to lowercase. It iterates through the input array and pushes the lowercase version of each string into a new array.

```javascript
const toLowerCase = input => {
const output = []
for (let i = 0; i < input.length; i++) {
output.push(input[i].toLowerCase())
}
return output
}
```
