Remap properties name and values using lodash

Question

I have this array:

aItems = [{
    \"PropertyA\": \"apple\",
    \"PropertyB\": \"banana\",
    \"PropertyC\": \"dog\",
    \"PropertyD\": \"hotdog\",
    \"         


        

Answer 1

Create a mapping of old and new keys, like this

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;
    });
});
