Interfaces constrain the values they contain to values whose type implements at least the methods specified in the interface.

The empty interface specifies no methods, so a value of any type satisfies it: they all implement at least no methods.

I guess that makes sense. I first saw this when reading about using an interface as a value in a map for json.

Go - can someone explain why empty interfaces can hold any value, where it seems "regular" interfaces only define functions? In other words, why can the empty interface hold something other than a function definition? new to Go and interfaces in general...
