Return empty list instead of null

Question

I want to change my current function to return empty JSON list, currently it returns nil.

This is my current code:

func (s *Service) pro

Another way to handle this is to check if the slice is nil and initialize it:

projects = ps
if projects == nil {
    projects = make([]*models.Project, 0)
}

This can be tedious if you have several structs and structs with arrays. To handle those, you can create custom marshalers or dynamically inspect fields.
