About the technology

Designed by Google with productivity in mind, Go excels in modern, highly-dynamic environments. This modern language has all its concurrency primitives baked in, so Go users can handle problems like real-time performance with no additional tools required. Its simple-but-powerful type system includes generics and interfaces as first-class citizens. Best of all, because Go was designed to be simple, with a small number of keywords and an efficient standard library, it’s really easy to learn! In a cloud-first world, it’s easy to see why Go has quickly become a must-have skill.
