Can I use _lodash to update an array with data from another?

I have an array called that has an assignedTo field which is a Id value (25 and 26) in this example. I also have another array called userProfiles that has an id and a name field.

var = [

var userProfiles = [

I have the following function:

var getUser = function (userId) {
if (userId && userProfiles)
for (var i = 0; i < userProfiles.length; i++)
if (userProfiles[i].id === userId)
return userProfiles[i].name;
return '';

Is it possible for me to use _lodash to call the getUser function with
the assignedTo values and replace the assignedTo with the user name
that's returned? Alternatively (if it's a better way), could I combine the and the $scope.option.userProfiles with _lodash and avoid having to call getUser?

This is the output I need:

var grid.newData = [

you could combine an and a _.where....

grid.newData =, function(item) {
    var profile = _.where(userProfiles, {id : item.assignedTo})[0];
    return {
        cityId : item.cityId,
        assignedTo :
