_.pluck

pluck_.pluck(list, propertyName)
A convenient version of what is perhaps the most common use-case for map: extracting a list of property values.

var stooges = [{name: 'moe', age: 40}, {name: 'larry', age: 50}, {name: 'curly', age: 60}];
_.pluck(stooges, 'name');
=> ["moe", "larry", "curly"]
