// Define a student object
let student = {
  name: 'CodeBuddy',
  age: 20,
};

// Output the values stored in the student object
console.log('Student\'s name: ' + student.name); // Student's name: CodeBuddy
console.log('Student\'s age: ' + student.age); // Student's age: 20

// Modify the values of the student object
student.age = 25;
console.log('Updated student\'s age: ' + student.age); // Updated student's age: 25

# Object

An object is a collection of data composed of key-value pairs.

Here, keys are strings and values can be of various data types (primitives, objects, functions, etc.).

<br />

## Creating an Object

In JavaScript, you can create an object using curly braces `{ }`.

You can represent your wallet as an object as shown below.

```javascript title="Creating a wallet object"
let wallet = {
  money: 10000,
  creditCard: 'Visa',
  photo: 'family photo',
  driver'sLicense: true,
};
```

Items like `money`, `creditCard`, `photo`, and `driver'sLicense` inside the object are called 'properties' or 'keys', and the values associated with these keys are called 'values'.

<br />

## Accessing Information from an Object

1. **Using the dot (`.`) notation**: This is the most commonly used method.

   ```javascript title="Accessing object information with dot notation"
   let myMoney = wallet.money; // 10000
   ```

<br />

2. **Using brackets (`[]`) with the key**: This method is useful when the key is given as a variable or contains spaces or special characters.

   ```javascript title="Accessing object information with brackets"
   let card = 'creditCard';
   let myCard = wallet[card]; // 'Visa'
   ```

<br />

## Modifying and Adding Information to an Object

To modify or add information to an object, you can use either the dot (`.`) notation or the bracket (`[]`) notation.

```javascript title="Modifying and adding information to an object"
// Adding new properties
wallet.height = 170;
wallet['creditCard'] = 'MasterCard';

// Modifying existing property values
wallet.money = 5000;
```

When using brackets to access an object's property value, you must input the property name as a string inside the brackets. Therefore, use `wallet['money']` to get the value of the 'money' property.
