Loops

Lesson: Loops

1. What is a loop?
   • A loop is a way to repeat a block of code.
   • Computers are fast, so we can repeat a block of code as many times as we want.
   • Most things we do with computers are done in loops.
2. Types of loops in Scratch:
   • Repeat () block for counting.
   • Forever block never stops never stoping.
   • Repeat Unitl () block for when you want to repeat until a condition is met.
