These five programming languages are useful for each mobile application developer. With them, you can create reliable, secure and popular applications.
Java
Since the advent of Java, it has become the main language for developing mobile applications on Android. It provides cross-platform support. In addition, Java applications are easy to migrate to different operating systems. Java applications work on the principle of "Written Once Run Anywhere" (WORA) - they will work the same on any Java-compatible device without the need to change the code. Although Java is a relatively old programming language, it remains popular.
Kotlin
Kotlin is the latest programming language fully compatible with Java. These two languages are interchangeable. Last year, Google called Kotlin "the main language for developing Android applications." Among the advantages compared to Java is Kotlin scalability.
Swift
Swift is a programming language developed by Apple as a modern replacement for Objective-C, which was previously used to create applications on iOS. Initially, Swift was intended for development on iOS, but now it can be used to develop applications for macOS, Windows and Linux. Unofficial tools for adding Android support are also available.
Rust
Rust is a relatively new language that has already become known for memory and security management capabilities. Like Java, Rust has cross-platform support and can be used to develop mobile applications on Android, iOS, Windows, macOS, Linux and for a number of varieties of Unix. Rust is suitable for the development of native and web applications, as well as operating systems, browser components and game engines.
HTML5
HTML5 is also on this list, although it is not a language for developing mobile applications - it is used to create web applications that run on any device through a browser. Applications written in HTML5 can be combined with frameworks that allow you to use APIs and, while preserving all the functions of a web application.
