};

You can add properties dynamically using some of the options below:

In you example:

var data = {
    'PropertyA': 1,
    'PropertyB': 2,
    'PropertyC': 3
};

You can define a property with a dynamic value in the next two ways:

data.key = value;

or

data['key'] = value;

Even more..if your key is also dynamic you can define using the Object class with:

Object.defineProperty(data, key, withValue(value));

where data is your object, key is the variable to store the key name and value is the variable to store the value.

I hope this helps!
