How Does The Async Await Episode I Promised Work?

You're waiting for your favorite snack to finish baking while you do something else, that’s how async await works.

Imagine you have a robot friend who can make pancakes. Normally, when you ask the robot to make pancakes, it stops everything and makes them right away. But with async, your robot says, “I’ll start making pancakes, but I won’t stop you from doing other things.” Then, when the pancakes are ready, you use await to say, “Okay, now let’s eat the pancakes.”

Without async await, it's like your robot has to wait for the pancakes to be done before helping you with anything else. But with async await, your robot can start making pancakes and then go help you clean up or play a game, all while still finishing the pancakes.

It’s like having a friend who starts drawing a picture, but doesn’t stop you from playing a game at the same time. When the picture is done, you both look at it together.

So async is “I’ll do this, but I won’t block you” and await is “Now let’s finish it together.”
