Coding Community | Golang

Go (often referred to as Golang) is a programming language created by Google in 2009. It is a statically-typed, compiled language that is designed to be efficient and easy to use, with a focus on concurrency and simplicity. It is similar to C and C++ in terms of performance, but with a more modern and expressive syntax. Go also includes built-in support for concurrency, making it well-suited for developing large-scale, concurrent systems. Some of the key features of Go include garbage collection, strict typing, and a built-in package manager. Go is used in a variety of applications, including web servers, networking tools, and data pipelines, and it is used by companies such as Uber, Netflix, and Google.
