1. Kotlin Overview

Kotlin is a modern static programming language that supports multiple paradigms and multiple platforms. Kotlin supports object-oriented, generic, functional, and other programming paradigms. It supports JVM, Android, and JavaScript target platforms, while Kotlin of Native platforms also released version 0.2 a few days ago. In addition, Kotlin has many modern (also known as the next generation) Static language features, such as type inference, multi-paradigm support, void expression, extended functions, and pattern matching. Therefore, the above description is no exaggeration. It is a very promising emerging language.

In addition, 100% Java interoperability enables Kotlin to work with existing tools/frameworks such as Dagger, Spring, and Vert. x integration can also migrate existing Java-based servers and Android projects to Kotlin step by step.

Design Objectives

Create a Java-compatible language that is safer than Java and can detect common traps statically. For example, reference a null pointer.
Make it simpler than Java by supporting variable type inference, higher-order functions (closures), extension functions, mixins and first-class delegation.
Make it simpler than the most mature competitor Scala Language

Conclusion: Kotlin is a new JVM-based programming language that is compatible with Java and more concise than Java and can detect common traps statically.

In 2017, Google I/O officially listed Kotlin as the official development language.

2. Learning Curve

Like most programming languages
Choose basic syntax> class and Object> function expression> type check> core library> Java operation.

3. Development Tools

Intellij IDEA is developed by JetBrains, and Kotlin is the language developed by JetBrains, so there is no doubtIntellij IDEA
Is the most suitable development tool.
Android Studio isIntellij IDEA plug-in implements Android development IDE. Similarly, it supports Kotlin development. In particular, after AndroidStudio3.0 is updated, Google officially supports Kotlin by default, without the need for plug-ins.
