The above form is discouraged by the creators of the language, who maintain that the form presented below has the same meaning and is more aligned with the philosophy of the language: The filter function returns all elements from a list that evaluate True when passed to a certain function. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. In particular, JavaScript defines a , (comma) operator in the context of a parenthetical expression. A method reference doesn't indicate the number or types of arguments because those are extracted from the abstract method of the functional interface. For example, a function for use in a Thread. Before 4.0.1, PHP had no anonymous function support. Internally, the function gets a generated name, of course; this generated name is based on the name of the method in which the Delegate is declared. C# v2.0, released in November 2005 with the .NET Framework v2.0, introduced the concept of anonymous methods as a way to write unnamed inline statement blocks that can be executed in a delegate invocation. are anonymous functions. This Church $\lambda$-abstraction, also called an explicit definition of a function, is used mostly when in the language of a theory there is danger of confusing functions as objects of study with the values of functions for certain values of the arguments. This is the part which caches the compiled form of the anonymous function, but it can only be invoked by being passed to the apply command. If unambiguous, the return type and the keyword delegate can be omitted. This example will compile in C# 3.0, and exhibits the three forms: In the case of the C# 2.0 version, the C# compiler takes the code block of the anonymous function and creates a static private function. In this example, a function that performs division by any integer is transformed into one that performs division by a set integer.
