You are working on a React project and have come across a code snippet for a component called `Demo`. Your task is to complete the implementation by adding some functionality to the `Demo` component.

The `Demo` component is a functional component written in TypeScript, and it is imported from another module. It takes no props and renders a single `<div>` element. However, the content of the `<div>` is currently left as a placeholder comment.

Your task is to modify the `Demo` component so that it renders a list of numbers from 1 to 10, inclusively. Each number should be wrapped in a `<span>` element, and there should be a space character between each number.

Your solution should be implemented by updating the `Demo` component and should not introduce any new components or libraries.

Sure, I can help you with that. Here's how you can modify the `Demo` component to render a list of numbers from 1 to 10:

```typescript
import React from 'react';

const Demo: React.FC = () => {
  return (
    <div>
      {/* Current implementation: empty */}
      {/* New implementation */}
      <ul>
        {Array.from({ length: 10 }, (_, index) => index + 1).map(
          (num) => (
            <li key={num}>
              <span>{num}</span>
            </li>
          )
        )}
      </ul>
    </div>
  );
};

export default Demo;
```

In this updated version, we first create an array of numbers from 1 to 10 (`Array.from({ length: 10 }, (_, index) => index + 1)`). Then, we use `map` to transform each number into a list item (`li` element) with a `span` inside. The `key` prop of `li` is set to the number to help React identify which list item to update when one of the props changes.

Note that this implementation assumes that JavaScript strict mode is not enabled because of the usage of `querySelectorAll` in `index`. If you're using strict mode, you'll need to use `Array.from` instead.

  const numbers = Array.from({ length: 10 }, (_, i) => i + 1);

  return (
    <div>
      {numbers.map((number) => (
        <React.Fragment key={number}>
          <span>{number}</span>
          {number !== 10 && ' '} {/* Add a space after each number, except after 10 */}
        </React.Fragment>
      ))}
    </div>
  );
};

export default Demo;
```

In this code, we first create an array of numbers from 1 to 10 using `Array.from()`. Then, we map over this array and for each number, we return a `React.Fragment` that contains a `<span>` element with the number and a space character (except after 10). The `key` prop is set to the number to ensure each list item has a unique key.
