Embed the script into HTML

I am trying to embed the JavaScript files into HTML file.

I have very simple example for test purposes

**test.html**
```

```

**script.js**
```
function testfn()
{
alert("hello world");
}
```

I expect, that I provide the HTML file name into Webpack, the webpack will detect the JS file and will generate this output standalone HTML file:
```

function testfn()
{
alert("hello world");
}

```

How to configure webpack to do this (**package.json** and **webpack.config.js** file)? I can not find, how to bundle such simple example.

The input HTML file is not an template. There is working page file.

Start by reviewing the requested inputs, test.html, script.js, package.json, and webpack.config.js, then check the plugin's configuration and documentation entry points. Determine whether embedding an existing HTML page and its referenced script is supported or requires a new feature. Done means the requested HTML produces a standalone file with the script embedded and the behavior remains covered by project tests.
