Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates the name of variables, functions, classes, packages, files, and URLs. Here is an example: "The hcf() function will freeze the system."

A block of code is set as follows:

fun main(args: Array<String>) = runBlocking {
    val time = measureTimeMillis {
 val name = async { getName() }
 val lastName = async { getLastName() }

 println("Hello, ${name.await()} ${lastName.await()}")
 }
    
    println("Execution took $time ms")
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

fun main(args: Array<String>) = runBlocking {
    val netDispatcher = newSingleThreadContext(name = "ServiceCall")

    val task = launch(netDispatcher) {
        printCurrentThread()
    }

    task.join()
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Please make sure that the Include Kotlin Support option is enabled."
