Sometimes, programs have to wait for something to finish before they can keep going! โณ
For example, if you are loading a picture from the internet, that might take a little
time.
Asynchronous programming allows our code to keep running while it waits!
In JavaScript, we can use something called
callbacks or
promises to handle this. A callback is like saying, "Hey, once you finish, call me back!" ๐ Here's a simple example:
```javascript
setTimeout(function() {
console.log("Thanks for waiting!");
}, 2000);
```
This code will wait 2 seconds before saying "Thanks for waiting!" It's like cooking a meal and chatting with friends while the food is cooking! ๐ฝ
