Golang was envisioned and created to simplify software development, especially in complex, multi-tenant applications with a large codebase. Go’s creators saw that other languages struggled with scalability and designed a language to ease developers’ work and improve processing times.
Engineers who share their experiences of switching to Go claim that it’s an excellent choice when it comes to codebase maintenance at scale and building functional microservices. All respondents appreciated Golang’s easy code review and deployment, as well as clear documentation.
