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.
