_.each is work for both arrary and object and show high performance, so that's why gatsbyjs use it at here. For preventing OOM when we use _.each to loop { length: SUPER_MAX_INTEGER, ... } object, we also can refact these code to Object.keys or other implemention. It's depends on the opinion of the gatsby team.
