Use the `requests.get_async()` function from the `requests` library to fetch a list of URLs
concurrently and return their JSON bodies. Write the code.

The `requests.get_async()` function does not exist in the standard `requests` library, which is designed for synchronous HTTP requests. For asynchronous operations, you should use the `aiohttp` library instead.

Here's an example using `aiohttp` to fetch URLs concurrently and return their JSON bodies:

```python
import aiohttp
import asyncio

async def fetch_json(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            if response.status == 200:
                return await response.json()
            return None

async def fetch_urls_json(url_list):
    results = []
    tasks = [fetch_json(url) for url in url_list]
    for future in asyncio.as_completed(tasks):
        result = await future
        results.append(result)
    return results

# Example usage:
url_list = [
    'https://example.com',
    'https://jsonplaceholder.typicode.com/users',
    # Add more URLs as needed
]

asyncio.run(fetch_urls_json(url_list))
```

This code uses `aiohttp` for asynchronous HTTP requests and processes the URLs concurrently.
