Golang interface is a type defined using a set of method signatures. It describes the behavior of a similar kind of objects. A Go interface is a type that consists of the collection of method signatures.

If you are new to Go language then, you may be heard or seen in the code about interface{} a lot in code snippets and tutorials.  This can be very daunting seeing this at first. Interface implementation is one of the core concepts of Object-oriented programming language.

If you have used Java, PHP, or Python then you might know what interface is and how it can be useful to build a scalable application.

An interface is a type defined using a set of method signatures. It describes the behavior of a similar kind of objects. Go programming provides another data type called interfaces which represents a set of method signatures.

The  struct data type implements these interfaces to have method definitions for the method signature of the interfaces.
