Function composition. In mathematics, function composition is the pointwise application of one function to the result of another to produce a third function. For instance, the functions f : X â Y and g : Y â Z can be composed to yield a function which maps x in X to g(f(x)) in Z.
Programming languages typically support a set of operators: constructs which behave generally like functions, but which differ syntactically or semantically from usual functions. Common simple examples include arithmetic, comparison, and logical operations. More involved examples include assignment, field access in a record or object, and the scope resolution operator. Languages usually define a set of built-in operators, and in some cases allow user-defined operators.
