Lambda functions are nothing but functions without a name. We used to call them anonymous functions. A function is basically passed into a parameter of a function call, but as an expression. They are very useful. They save us a lot of time by not writing specific functions in an abstract class or interface.
Lambda usage can be as simple the following code snippet, where it seems like we are simply binding a block an invocation of the helloKotlin function:
fun main(args: Array<String>) { val helloKotlin={println("Hello from KotlinBlueprints team!")} helloKotlin() }
At the same time, lambda can be a bit complex as well, just like the following code block:
fun <T> lock(lock: Lock, body: () -> T): T { lock.lock() try {
