In the development sector, the new language emerging, including the go, Rust, Nim, Julia, Scala, Swift ... the list could pull very long, but never a cause such as Kotlin language as widely discussed.
In StackOverflow website statistics, most developers welcomed the list of programming languages, Kotlin got 72.6% of the high proportion of support, ranked fourth. According to a global survey of programmers JetBrains said: one-third of developers are planning to migrate their existing projects to Kotlin.
▲ including the United States, South Korea, Britain and other more than 7000 participated in the survey -
And that 92 percent of users had previously been Kotlin language JAVA language users. Why JAVA developers are so fond of Kotlin?
I feel in use, and Kotlin addition to the existing Java code seamless interoperability, the architectural components in these applications Andrews, network requests a database operation, with at least Kotlin are reduced 1/3 lines of code. I generally summarized below:
1. simplicity, reduced boilerplate code to improve development efficiency;
2. native functional programming supports object-oriented programming support coroutine;
3. Compatible JAVA, 100% highly interoperable, and can exist in the same and JAVA programs ;
4. safer, capable of detecting static common pitfalls, such as a null pointer references;
5. easy to maintain, by the native gene JetBrains, destined to support a variety of tools and is the IDE;
In addition, the current mobile platform to do cross-platform development, then, react native and Flutter are two options momentum Flutter may be a little better, but also Kotlin Native rapid development, we have been able to develop applications on iOS, future Kotlin outlook statement is very good.
Before the Scala might be a small part of the people's choice, but Kotlin learn from this modern Scala language, more push Google, and the whole community, Kotlin is certainly completely replace the choice of the Scala.
If you are a developer Mingan Zhuo, in addition to the continued use of some of the previous Java libraries, Kotlin must be indispensable.
With May of this year, Google IO Conference officially announced the Android Kotlin is the preferred development language, and even 50% of Android developers have started using Kotlin language. This will lead to more Android library corresponding emergence of Kotlin realize, perhaps even only Kotlin version, Android Studio IDE will be more inclined to Kotlin features and support.
While the corresponding in actual business, companies are constantly promoting migration to JAVA Kotlin, many developed for Android JD require the programmer will Kotlin.

In the past three years, I was in charge of the development team are using Kotlin, especially in the current project is almost 100% Kotlin. I recruit team members this year, if not Kotlin experience will be a strong emphasis on the ability to learn a new programming language.
So, I worked with rookie nest launched such a "Kotlin from entry to the actual" course systematically covers the beginning of Kotlin, intermediate and advanced knowledge, hoping to help JAVA / Android developers to quickly grasp Kotlin, and can really application in practical work.
I am a senior architect Travis Travis, master degree in 1997 up to now, has counted 22 years of software development experience, worked in Motorola, Nokia, Polycom and other corporate career proficient in JAVA / Ktlin / C / C ++ and other languages, and more familiar kinds of mobile development platform (Android / IOS / embedded Linux / Symbian / Windows Phone).
As an "old farm yard," I experienced a lot of changes in mobile technology platforms, from 99 earliest Symbian developer, 02 years of embedded Linux mobile platform, the 2008 comprehensive restructuring Android platform, I try through multimedia, e-commerce, tools and other kinds of applications, and is still continuing to explore the Android platform technology from the bottom to the top.
在这门课程中，我希望利用自己在多种移动平台的开发经验，通过对比不同语言的特性，让你快速并上手Kotlin，提高安卓开发的效率，在未来职业道路上也能够收获更多。《Kotlin快速入门与实战》听课视频入口☞https://www.cniao5.com/course/10228
《Kotlin快速入门与实战》包含十七大章节50个小节，在这门课中，我将以完全新手的角度，从Kotlin的基本语言特性和优点出发, 注重实战技巧, 让你逐步掌握面向对象编程和函数式编程的思想。
而且，我会通过一个完整的安卓APP项目来讲解Kotlin带来的开发效率提升。在高级阶段，也会对软件架构、DSL、 跨平台开发等有所总结。学会Kotlin, 不止于Kotlin!
