Go, also known as Golang, is an open-source, statically typed, compiled programming language designed at Google with a focus on simplicity, efficiency, and reliability. It is particularly renowned for its built-in support for concurrency through goroutines and channels, making it an excellent choice for developing scalable network services, distributed systems, and cloud-native applications. Go combines the performance of lower-level languages like C++ with the readability and developer-friendliness of modern, higher-level languages, supported by a robust standard library and powerful tooling.
