Run Returns

Use run to calculate a value from a short local block.

RunReturns.kt

fun main() {
    val width = 
    val area = run {
        val height = width + 1
        width * height
    }

    println("width=$width")
    println("area=$area")
}

fun main() {
    val width = 
    val area = run {
        val height = width + 1
        width * height
    }

    println("width=$width")
    println("area=$area")
}

fun main() {
    val width = 
    val area = run {
        val height = width + 1
        width * height
    }

    println("width=$width")
    println("area=$area")
}

run `run` groups a calculation and returns the last expression in the block.
