Folder Structure, along with the purpose :-

• /app/     -      It contains the controllers, models, views and assets for your application. This is where the majority of the code for our application will live. We will be spending most of our time in this folder.

• /public/   -    The only folder seen to the world asis. This is the directory that we have to point our web server to. It contains the bootstrap file "index.php" which jump starts the Laravel framework core. The public directory can also be used to hold any publicly accessible static assets such as CSS, Javascript files, images and other files.

• /vendor/    -   A place for all third party code. This includes the Laravel source code and its dependencies, and plugins.
