title: Declare JavaScript Objects as Variables
|
|
---
|
|
This has a simple format. You declare your variable and have it equal to an object in the form `{ key: value}`
|
|
|
|
var car = {
|
|
"wheels":4,
|
|
"engines":1,
|
|
"seats":5
|
|
};
|
|
|
|
You can access the object's properties using dot notation or bracket notation.
|
|
|
|
Using dot notation:
|
|
|
|
```javascript
|
|
console.log(car.wheels); // 4
|
|
```
|
|
|
|
Using bracket notation:
|
|
```javascript
|
|
console.log(car["wheels"]); // 1
|
|
```
|
|
|
|
Using dynamic bracket notation:
|
|
```javascript
|
|
var seatsProperty = "seats";
|
|
console.log(car[seatsProperty]); // 5
|
|
```
