Server-side scripting is a coveted feature for back-end web development, as it garners better SEO results. Either way, you will need Kotlin developers to manifest such a project in real-time. Inlining, or inline expansion, is a feature of functional programming that allows for a short line with a function call to be expanded to the full body of the function.

Who This Book Is ForThis book is for anyone who would like to leverage the power of version control with Git in their software development process. It then moves on to walk you through creating a new repository, cloning an existing one, merging in changes, and all of the bits in between.

• Android is inherently asynchronous and event-driven, with strict requirements as to on which thread certain things can happen.

Though Kotlin is both functional and object-oriented, functional programming offers some interesting perks. Functional programming permits developers to build software by using functions, where each function returns a value. If you want to advance your Kotlin development skills, you need to get your hands dirty working on a project like the Tic Tac Toe game. While this game is extremely easy to play, developing its application is quite challenging for entry-level developers.

You can use Kotlin for developing not only Android but also iOS, backend, and web applications. To start from scratch, create a basic cross-platform mobile application with the project wizard. You may also be interested in low code or no code platforms to build mobile apps for business or personal use. This book discusses all the major components of Kotlin so that readers can successfully implement this language to develop apps for various platforms.

If you are starting a new project with Gradle or Maven, your IDE probably can generate the required files for you.

For the output variable, the Kotlin compiler infers the type Long based on the function’s return type. You may prefer to use explicit types for clarity.Especially when the right-hand side is a complex expression or function call. Type inference is a compiler feature that allows you to omit types Kotlin developer job in your code when the compiler can infer it for you.
