ELI5: Explain Like I'm 5

Prototyping

Prototyping is just like playing with toys before you buy them. When you want to make something new, you can't always know exactly how it will work. So, you make a special version of it that you can play with and test out. This version is called a prototype. It helps you figure out what you like, what you don't like, and how you can make it better. It's like drawing a picture before you paint it. That way, you can see if everything looks good together before you start adding colors. Prototyping is a fun and important part of making something new.
