Kotlin fully supports all major integrated development environments (IDEs) that are used for Java development as well as many text editors. This makes code appear shorter and cleaner. Kotlin supports two kinds of type inference: local type for types of expressions locally in statement or expression scope and function signature for inferring types of function return values and parameters. When making a web application with Kotlin, a developer doesn’t need to specify explicitly the type of each variable – some data type information can be safely omitted and identified by the compiler. The solution decreases the number of errors and makes coding easier. Instead, it uses a safe call operator (?.) to check for null references it executes any action only if the reference has a non-null value. In Kotlin, a developer cannot directly assign null value to any object or variable. The problem that many Java developers are familiar with is NullPointerException that happens when accessing null reference from code and causes runtime errors and crashes. Less code and more concise syntax mean fewer bugs would find their way into the final version of the app, while Kotlin’s readability makes it easier to fix issues and maintain the code. On average, code in Kotlin is 40% shorter than the same code in Java. Compared to Java, Kotlin is more understandable and requires fewer lines of code. It can be used to develop apps for a server, web browser, or mobile. Kotlin is a full-stack solution that can be used for back-end and front-end development instead of Java and JavaScript. In the article, we’ll cover the benefits of the Kotlin programming language and what features make it an outstanding choice for building a web application.
We at Surf have been developing apps for over a decade, using both native and cross-platform technologies for our projects. However, Kotlin is also a great language for web development. Since Google announced Kotlin as a language of choice for Android development in 2019, the majority of Android app developers switched to it, making it the fourth most loved programming language.
It is designed to be fully interoperable with Java, meaning that it compiles into the same bytecode as Java and can execute its code. Val throwables = listOf(e, *e.suppressed)īut in practice, you're probably not going to react differently to various IOExceptions, so you can just put the one try/catch outside.Introduced by JetBrains in the 2010s, Kotlin is an open-source general-purpose programming language.
