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:

myObject['myProperty'] = "myValue";

Using bracket notation, we can utilize variables as property names:

var dynamicProperty = "myProperty";
myObject[dynamicProperty] = "myValue";

We can also delete them like this:

delete(myObject.myProperty);
