When I was a little boy, I loved playing with alphabet blocks. Bet you did also. Well, App Inventor brings that joy back—we get to play with blocks again!
Blocks of code, but we never have to see the code, let us tell the components what we want them to accomplish. It's all visual now, dragging-and-dropping blocks on our computer screen into various simple configurations.
We're actually programming (shhh! Don't tell anyone!). It doesn't look like programming, and you certainly don't have to know much about programming technicalities to create powerful and complex programs (that is, in operations and not in the building of them).
Blocks are simply the logic that instructs the component services how to act and in what order tasks happen.
In this chapter, we look at the types of blocks and how they are used, and find our way around in the App Inventor Blocks Editor.
In this chapter, specifically, we will learn:
