As Moore’s Law is reaching the end of its lifecycle, the need for concurrency is rising and consequently, the need for a programming language that enables effective implementation of concurrent programs is rising too. For this reason, Go has become one of the most popular languages in recent times. This course aims to provide a detailed introduction to Go for beginners. Furthermore, it also articulates how Go is different from traditional programming languages that programmers are accustomed to in order to acquaint programmers getting ready to delve into Go with the language too.

An Introduction to Programming in Go

### Definition

An __interface__ type is defined by a set of methods.
A value of interface type can hold any value that implements those methods. Interfaces increase the flexibility as well as the scalability of the code. Hence, it can be used to achieve polymorphism in Golang. Interface does not require a particular type,  specifying that only some behavior is needed, which is defined by a set of methods.

### Example

Here is a refactored version of our [earlier example](https://www.educative.io/courses/introduction-to-programming-in-go/introduction-qV38M2GZL0p).
This time we made the greeting feature more generic by defining a
function called `Greet` which takes a param of interface type `Namer`.
`Namer` is a new interface we defined which only defines one method:
`Name()`. So `Greet()` will accept as param any value which has a
`Name()` method defined.

To make our `User` struct implement the interface, we defined
a `Name()` method. We can now call `Greet` and pass our pointer to `User` type.

This lesson gives an introduction to interfaces in Go using an example, also explains how to define a new type that would implement the same interface.
