Imagine you are building a toy house with blocks. You can just stack the blocks on top of each other, but it might not look very organized or easy to understand.
A structure editor is like having a special tool that helps you build the toy house in a more organized and efficient way. The tool has different shapes and colors of blocks that you can select and snap together in specific ways to create different parts of the house like walls, doors, and windows.
The structure editor lets you see how all the blocks fit together and helps you avoid mistakes. It also helps you rearrange and modify parts of the house easily without having to start from scratch.
In computer programming, a structure editor is a tool that helps developers create and modify the structure of their code. Instead of writing code manually, the structure editor lets them select and drag and drop different pieces of code to create a program. This makes programming faster and more efficient.
