Go, often referred to as Golang, is an open-source programming language developed by Google. Designed for efficiency, simplicity, and concurrency, Go combines the speed of a compiled language with the ease of a dynamically typed one. It emphasizes clear syntax, automatic memory management, and a robust standard library. Golang excels in building scalable and high-performance software, making it a popular choice for web services, network applications, and distributed systems. Its built-in support for concurrent programming through goroutines and channels simplifies parallelism. With a strong focus on simplicity and efficiency, Golang has gained traction in modern software development.
