CRUD Operations with JavaScript Objects

While learning JavaScript objects, I practiced a simple concept that appears everywhere in software development: CRUD.

CRUD stands for:

Create → Add data
Read → Access data
Update → Change data
Delete → Remove data

Let's use a vehicle object as an example.

const vehicle = {
    model: "KTM 350",
    price: 200000,
    fuelType: "Fuel",
    cc: 350,
    drive: function() { 
    console.log("Speed: 150 km/h"); 
    } 
};

1.Create

Add a new property:

vehicle.gear = 6;

2.Read

Access existing data:

console.log(vehicle.model);
console.log(vehicle.price);

We can also call a method:

vehicle.drive();

3.Update

Change an existing value:

vehicle.price = 210000;

4.Delete

Remove a property:Use delete key word

delete vehicle.cc;

Now the cc property no longer exists.

The basic idea

Create → vehicle.gear = 6
Read → vehicle.model
Update → vehicle.price = 210000
Delete → delete vehicle.cc

This simple example helped me understand that CRUD isn't only related to databases or APIs.

The same four operations can be practiced directly with JavaScript objects.

I'm building my JavaScript fundamentals one concept at a time.
