Nodejs - Correct way to iterate through nested JSON array

Question

Consider the following sample JSON array:

[{
    info: {
        refOne: 'refOne',
        refTwo: [{
            refOne: 'refOne',
            refTwo: 'refTwo'
        }]
    }
}, {
    info: {
        refOne: 'refOne',
        refTwo: [{
            refOne: 'refOne',
            refTwo: 'refTwo'
        }]
    }
}]

The above JSON is a simple representation of a database query response, What is the correct way within Nodejs to loop through each 'refTwo' array within the parent info array?

sudo example: for each item in sample JSON for each refTwo item in current item do something

I have a suspicion that the 'async' lib may be required here but some advice is much appreciated.

This is a simple javascript question:

var o = [...];

var fn = function (e){
    e.refOne...
    e.refTwo...
};

o.forEach (function (e){
    e.info.refTwo.forEach (fn);
});
