REST services are trivial in the modern web. SOA (which we discuss in more detail later) created an activity space for REST services to take web development to the next level. Go is a programming language from the house of Google for solving the bigger problems they have. It has been eight-plus years since its first appearance. It matured along the way with a developer community jumping in and creating huge scale systems in it.

One can choose Python or JavaScript (Node) for their REST API development. The main advantage of Go lies in its speed and compile-time error detection. Go is proved to be faster than dynamic programming languages in terms of computational performance by various benchmarks. These are the three reasons why a company should write their next API in Go:

• To scale your API for a wider audience
• To enable your developers to build robust systems
• To invest in the future viability of your projects

You can look at the neverending online debates for more information about REST services with Go. In later chapters, we try to build the fundamentals of designing and writing the REST services.
