Java Programming A Practical Approach C Xavier Pdf
Functional programming uses special syntax to avoid using imperative programming, but does not require any particular programming paradigm. Thus many functional languages can use the same notation as imperative programming such as loops, variables, and conditionals. Languages that cannot use imperative programming typically use a functional style that goes beyond mere avoiding side-effects.
The dual notion of functional and imperative programming has some confusing aspects. For example, you compose functions from right-to-left, whereas you can think of functions from left-to-right. Some functional languages are even order-independent, which means that the result is equivalent to the order you multiply the arguments in, not necessarily just associating with previous arguments.
An intermediate layer, known as a ”functional programming or FP” layer, may be included, as in Lisp and CLOS. This layer focuses on representing the functional style and implementing the functional operations in the usual (imperative) programming style. Sometimes, the expressions representing a functional style are executed using an interpreter or just-in-time compiler (JIT).
An early example of functional programming is denotational semantics. Denotational semantics evaluates a functional programming language by modelling the semantics of its modules (functions) as the properties of functions. From the perspective of denotational semantics, a functional programming language is a way of describing a mathematical function, or type class. For example, the definition of a one-argument function
F n in a functional programming language may be given by a definition of the type class
Various other notions of functional programming utilize the principle of referential transparency to support computations that are deterministic, rather than purely a matter of convention. The concept originates in the programming languages ML and Haskell.
