We’ve already seen one type of loop used in Scratch, the forever loop. As the name “loop” implies, a loop repeats the code in its body. Loops are useful when programmers want to run code multiple times, but don’t want to write the same code over and over again.
If-statements are used to make programs more efficient. In this article, we will be defining and exploring the function of this concept. Log into your Scratch account and create a new project. We will use the simple project set up with one sprite.
Let’s write a program that makes two sprites dance around to some music. Note: Please make sure to periodically save your project using the “Save Now” button in the toolbar to avoid losing your work!
Scratch is a website that allows users to create games and animations while introducing many basic concepts that are used often in programming, such as functions and loops. Scratch itself can also be considered a programming language.
Devices used for computation have been around since before 1000 BCE. However, these predecessors to the modern computer, such as the abacus, depended on physically manipulating rods or beads that represented numbers to perform mathematical calculations. Where did computing come from?
