Golang, also known as Go, is an open-source programming language developed by Google in 2007. It is designed for simplicity and efficiency, making it easy for developers to write clear and maintainable code. Golang is particularly well-suited for building web servers, cloud services, and other applications that require high performance and concurrency. One of the key features of Golang is its built-in support for concurrent programming, allowing multiple tasks to run simultaneously without complex threading models. This makes it a popular choice for modern software development, especially in environments where speed and scalability are crucial.
