What is Reflection APIs?

Reflection APIs are like superpowers that let a program look at itself and change how it works, just like you can peek inside a toy box and rearrange the toys.

Imagine you have a robot friend who can play with blocks. Normally, you tell the robot what to do, like "stack red blocks" or "line up blue blocks." But with Reflection APIs, the robot doesn’t need instructions for every block. It can look at the blocks, see their colors, and decide how to stack them on its own.

Think of your robot as a smart toy box. When you open it, you can see all the toys inside, what kind they are, what color they are, and even what size they are. With Reflection APIs, the program acts like that smart toy box, it can look at other parts of itself, like functions or variables, and use that information to do cool things.

This is like having a magic mirror in your toy box, you can see all the toys inside, and sometimes even change how they work! Programs use Reflection APIs to make themselves smarter, like when apps learn from you as you use them.
