How do I enumerate the properties of a javascript object?

If I have a javascript object like this :

data = {

    a : 2,

    b : 3

}

but a and b are arbitrary and decided at runtime. Is there any way to go through the object
and access all properties without knowing the key?

data = {

    a : 2,

    b : 3

}



for(var propName in data) {

    if(data.hasOwnProperty(propName)) {

        var propValue = data[propName];

        // do something with each element here

    }

}
