+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);
