For example, compared to Java, a software written in Kotlin is expected to have roughly 40% less lines of code, while still being able to interoperate with the rich set of libraries available for Java.

One of its main goals is to solve the problems that comes along with Java.

This programming language is statically typed, which means that variables, functions, and expressions use predefined sets of types that can be checked on compile time. Kotlin is a programming language, developed by JetBrains, that runs on Java Virtual Machines (JVMs) and that can also be compiled to JavaScript. In the end, we will also see how to manage the JWTs by ourselves, replacing Auth0 with an in-house solution where we issue our own tokens. After that we are going to secure this API with Auth0, which brings to the table many security features such as Multifactor Authentication, integration with Social Providers, and so on. We will start by creating a small Spring Boot RESTful API that handles CRUD operations. TL DR: In today's post, we are going to learn how to develop RESTful APIs with Kotlin, the thriving programming language that is eating Java's world.
