Why every PHP Developer should learn Golang

Being a PHP/Laravel Developer, amongst other programming languages like Ts, C#, I've been using the OOP approach to abstracting domain of projects. With Golang, the perspective is now something different from what you know. Golang is a very powerful language that is easy to learn and has only the necessary constructs required to be applications. The most obvious aspect of Go, is its approach of using composition over OOP. If you're new, your head will crack a little because there is no place where you would see that an interface is explicitly implemented unless you know how it works.
