In programming, a lambda, or lambda expression, generally refers to anonymous functions (functions without names or declarations). In Kotlin, a lambda expression starts with { and ends with }. It is called the anonymous function/lambda expression, since it doesn't contain a formal function declaration/name, but, rather, uses something more like a variable, containing an expression for a computation. Note that every lambda is a function, but every function might not be a lambda.
Lambda is strictly a language feature that isn't supported by all languages; for instance, Java didn't have support for lambda expressions till Java 8 came out, and till then, it only supported anonymous objects (instances of classes) for lambda, and not anonymous functions; in other words, you first had to create an interface, and only then could you pass...
