Re: [go-nuts] Pass by value in struct not yielding expected result

In that case, for a nested struct from top to bottom, all the values are copies as values, correct? i.e, string, int, float, array etc will be copied by value & map, slice, channel etc will be copied as pointers if they are initialized? https://play.golang.org/p/NzH8LVyQ0rp code works as I wan

Re: [go-nuts] Pass by value in struct not yielding expected result

maybe this will give you a hint: https://play.golang.org/p/ANIjc3tCdwp maps are reference types, but they still get passed by value. if you pass a nil map around, the old value you passed will not magically start pointing to a new map once you instantiate it elsewhere. -- You received this messa

go version 1.10 Operating system and processor architecture GOHOSTARCH="amd64" GOHOSTOS="darwin" However, this happens in play.golang.org env as well. Checkout the code. https://play.golang.org/p/v6u7R_nbGRp In the example, if the struct (Document) is not initialized at first, there is no pl
