[Aveeva]

I am using the following condition and its print one value,

if(self.options.nearestlocationsBlock) {
    var firstStore = _.first(locations.items);

    var newContent = '<div class="store"> <div class="zipcode">'+firstStore.address+','+firstStore.city+','+firstStore.state+','+firstStore.zip+'</div></div>';     

    self.storeListIdentifier.html(newContent);
} 

I want to print the next three values, how to do that?

eg: I am print first value, i want to print next three values in second condition, how to do that?
