Chapter VII · Objects
Properties
Properties are key-value pairs stored inside an object representing its attributes or data state.
01 How It Works
Think of labeled storage slots inside a filing cabinet drawer.
Keys map to values of any valid data type using dot or bracket notation.
example.js
const car = { brand: "Toyota", year: 2023 };
console.log(car.brand);1. Target the host object.
2. Specify the property key identifier.
3. Retrieve or update its associated value.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
const user = { role: "admin" };
user.active = true; // Adding propertyKey Takeaway
Properties hold the state data inside objects.
