nodejs, mongodb get array of only specified fields value

Question

Is it possible to get an array of a specified fields value in mongodb?

Like instead of getting:

[{"color":"blue"},{"color":"red"}]

I would like to get:

["blue","red"]

Is this question clear enough?

Answer 1

You can run array.map on the results array to achieve the desired result:

var colors = [{"color":"blue"},{"color":"red"}].map(function(obj){
    return obj.color;
});
