How to Create Custom Blocks (Functions) in MIT Scratch

In this Scratch coding tutorial, I will show you how to create Custom Blocks in Scratch which is the Scratch version of creating a Function. And functions are a fundamental part of coding and a crucial element in following the DRY principle (Don't Repeat Yourself) so if you want to become a better programmer and figure out how to use Custom Block/Functions in MIT Scratch to code more efficiently then this video is for you.

We'll cover it all from the basics of making a block/function, to passing in parameters, to parameter types, to adding labels, and understanding the local scope of variables within blocks/functions.

It's a bit of a long tutorial so here are some quick links for easy jumping around:
