Follow these steps:

$-$ Create a full$-$stack web application in a project directory called "carlnventory". Create the back$-$end of the application using Express and the front$-$end using React. You should create a MongoDB that stores information about cars in a collection called cars.

$-$ Your application should allow one to:

$-$ Add a car to the cars collection.

$-$ Update information about a single car.

$-$ Update information about more than one car.

$-$ Delete a specific document.

$-$ List all the information for all cars in your database.

$-$ List the model, make, registration number, and current owner for all cars older than $5$ years.

$-$ For the back$-$end of your application, ensure that you:

$-$ Install Mongoose.

$-$ Create $2$ directories in your project directory called "models" and "controllers".

$-$ Write all the code needed to perform the necessary CRUD operations for your application.
