middleware : Imagine these as helpers that help your website do things like checking if you’re logged in or keeping a record of what people do on your site.

models : This is where you describe what your data looks like. If your website is a store, this is where you say what a product is or what a customer is.

routes : These are like the paths to different parts of the website. If the website is a city, these are the streets and highways.

public : Think of this as your storage room for things everyone can see, like images, styles, and scripts.
