Imagine you have a bunch of Lego pieces and you want to make a toy car. You have to snap each Lego piece together in a certain order to make the car just right.
Snaps work the same way but with computer programs. Snap is a program that helps you put parts of different computer programs together to make a new program that works just the way you want it to.
Using snap is like clicking together all the different Lego pieces in a row, but instead of Lego, it's computer programs. Snap helps you put them together in the right order and make sure they work the way you want them to.
So, if you want a program that can help you draw pictures, you might snap together different parts of different programs that help you draw shapes, fill colors, and add text. Once they're all snapped together in the right order, you have a new program that can help you draw pictures just the way you want them!
