The concept of microservices supports using different languages for different services within a single application. This means the choice of programming language for each service can be based on its specific needs and functionalities. For example, you’re able to implement microservice A using C# but microservice B using JavaScript. That is the beauty of microservice development, which allows us to bypass programming language barriers.

This book is about writing microservices in JavaScript. As in any programming language, before implementing the microservice approach, it is best to understand the basics of the given language, which will help us to build better and more effective microservices. The focus of this chapter is to provide the foundation, rather than a comprehensive guide, for...
