javascript - Remap properties name and values using lodash -

i have array:

aitems = [{     "propertya": "apple",     "propertyb": "banana",     "propertyc": "dog",     "propertyd": "hotdog",     "propertye": "coldcat",     "propertyf": "y",     "propertyg": "n" }, ..., {     "propertya": "this",     "propertyb": "is",     "propertyc": "json",     "propertyd": "code",     "propertye": "wow",     "propertyf": "n",     "propertyg": "n" }] 

i use lodash obtain result:

aitems = [{     "propertya": "apple",     "propertyb": "banana",     "propertyc": "dog",     "propertyd": "hotdog",     "propertye": "coldcat",     "propertynew": true,     "propertyg": false }, ..., {     "propertya": "this",     "propertyb": "is",     "propertyc": "json",     "propertyd": "code",     "propertye": "wow",     "propertynew": false,     "propertyg": false }] 

i want map each property name other names , change value specific properties. can using lodash?

create mapping of old , new keys, this

var keymapping = {'propertya': 'propertya', ..., 'propertyf': 'propertynew'} 

and mapping of old , new values, this

var valuemapping = {'y': true, 'f': false} 

and using _.map , _.transform, can transform object, 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;     }); });
