The Python docs give this code example:

import asyncio

async def main():
    print('Hello ...')
    await asyncio.sleep(1)
    print('... World!')

asyncio.run(main())

Why is main called inside the asyncio.run() (and in other asyncio functions like asyncio.gather())?

It confuses me, because in JavaScript, we do things like document.addEventListener('click', someFunction) – we pass someFunction, not its result.
