But {{{1|}}} will evaluate to the empty string (a false value) because the vertical bar or pipe character, "|", immediately following the parameter name specifies a default value (here an empty string because there is nothing between the pipe and the first closing curly brace) as a "fallback" value to be used if the parameter is undefined.
The yield statement, which returns a value from a generator function (and also an operator); used to implement coroutines; The return statement, used to return a value from a function; The import and from statements, used to import modules whose functions or variables can be used in the current program
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method. [1] In many programming languages (especially statically-typed programming languages such as C , C++ , Java ) the return type must be explicitly specified when declaring a function.
$# (the number of parameters) $0 (this function name) OCaml: foo parameters: let «rec» foo parameters = instructions: let «rec» foo parameters = instructions... return_value: F# [<EntryPoint>] let main args = instructions: Standard ML: fun foo parameters = ( instructions) fun foo parameters = ( instructions... return_value) Haskell: foo ...
A specific element x of X is a value of the variable, and the corresponding element of Y is the value of the function at x, or the image of x under the function. A function f , its domain X , and its codomain Y are often specified by the notation f : X → Y . {\displaystyle f:X\to Y.}

A value of a variant type is usually created with a quasi-functional entity called a constructor. Each variant has its own constructor, which takes a specified number of arguments with specified types. The set of all possible values of a sum type is the set-theoretic sum, i.e., the disjoint union, of the sets of all possible values of its variants.
