Async/await

Async/Await is a way for a computer program to do multiple things at the same time.
When we tell a computer to do something, we send it instructions one step at a time. Async/Await lets us tell the computer to do multiple instructions at the same time, and wait for all of them to be finished before proceeding.
Think of it like a restaurant: when you order your food, you can also order a drink and appetizer. If the restaurant uses async/await, they can start preparing your drink and appetizer while they wait for your main meal to get ready. That way, everything will arrive to your table at the same time.
