Go Language Practice Exam

Go, also known as Golang, is an open-source programming language from Google. It was designed to be simple, efficient, and highly scalable, particularly for concurrent programming and handling large-scale systems. Go is suitable for creating web servers, networking tools, and cloud-based applications as it provides fast compilation and efficient runtime. It also provides goroutines (for concurrent programming) and channels (for synchronization).

Certification in Go Language certifies your skills and knowledge in using Go for building applications. This certification assess you in concurrency, error handling, testing, and Go’s unique memory management.
Why is Go Language certification important?
