title: Manipulate JavaScript Objects
|
|
---
|
|
There are a couple ways to manipulate object properties, dot notation and bracket notation.
|
|
|
|
Adding properties to objects with dot notation:
|
|
|
|
myObject.myProperty = "myValue";
|
|
|
|
Adding properties to objects using bracket notation:
|
|
```javascript
|
|
myObject['myProperty'] = "myValue";
|
|
```
|
|
|
|
Using bracket notation, we can utilize variables as property names:
|
|
|
|
```javascript
|
|
var dynamicProperty = "myProperty";
|
|
myObject[dynamicProperty] = "myValue";
|
|
```
|
|
|
|
We can also delete them like this:
|
|
|
|
delete(myObject.myProperty);
|
