Is there any way to rename js object keys using underscore.js

Question

I need to convert a js object to another object for passing onto a server post where the names of the keys differ for example

var a = {
    name : \"Foo\",

It's been solved here https://stackoverflow.com/a/30940370/1360897

var keyMapping = {'PropertyA': 'propertyA', ..., 'PropertyF': 'propertyNEW'}

and also a mapping of old and new values, like this

var valueMapping = {'Y': true, 'F': false}

And then using _.map and _.transform, you can transform the object, like this

var result = _.map(allItems, function(currentObject) {
    return _.transform(currentObject, function(result, value, key) {
        if (key === 'PropertyF' || key === 'PropertyG') {
            value = valueMapping(value);
        }
        result[keyMapping[key]] = value;
    });
});
