0:14
Ever feel like the world is just too much, too many details, too many things to remember?
0:21
Well, guess what?
0:22
There's a superpower that can help you make sense of it all.
0:26
It is called abstraction.
0:30
Abstraction is when we focus on the most important details and ignore the things that don't matter
right now.
0:40
Abstraction is like taking a big messy picture and turning it into a simple sketch.
0:47
It's about focusing on the most important parts and ignoring everything else.

Think of it like this, instead of drawing every tiny bolt and wire of a car, we just draw the wheels, the
body, and the steering wheel.
1:03
We get the idea without all the fuss.
1:08
This is an example of a complex car with a lot of detail.
1:14
This is when abstraction has been applied.
1:20
Think about a car's dashboard.
1:22
You don't need to see how the engine works to drive the car.
1:26
You just need the steering wheel, pedals and speedometer.
1:30
Abstraction hides the complicated parts and only shows you what is important.
1:39
Abstraction is about filtering out the unnecessary so the important bits stand out.
1:47
You use abstraction every day.
1:50
Maps are abstract versions of real places.
1:54
Icons on your phone are abstract pictures of apps.
1:58
You do not see all the code, only the icon and when you click on it you can use it.
2:04
Summaries are abstract versions of long stories.
2:08
Even when you use a mouse to move the arrow on the screen, you are using abstraction.
2:15
The computer is doing complex calculations and you are just moving an arrow.
2:23
If we think about coding for example, abstraction allows us to use blocks of code to do complex
things without having to write every single line.
2:37
Now it is your time.

You are going to try this yourself.
