The outputs are also declared as outputs. Pure functionĪ ‘Pure function’ is a function whose inputs are declared as inputs and none of them should be hidden. This technique applies a function to its arguments one at a time, as each application returning a new function which accepts the next argument. Higher-order functions allow partial applications or currying. Higher-order functions either take other functions as arguments or return them as results. The closure is an inner function which can access variables of parent function’s, even after the parent function has executed. Therefore, first-class functions can appear anywhere in the program.
‘First-class function’ is a definition, attributed to programming language entities that have no restriction on their use. Maintainability is a simple term which means FP programming is easier to maintain as you don’t need to worry about accidentally changing anything outside the given function. Apart from it, the modules can be tested separately which helps you to reduce the time spent on unit testing and debugging. Small modules can be coded quickly and have a greater chance of re-use which surely leads to faster development of programs. In FP term it is called Referential transparency. So, you will know what may or may not have happened during the program’s execution, and its side effects. Referential transparencyįunctional programs should perform operations just like as if it is for the first time. Immutable Data means that you should easily able to create data structures instead of modifying ones which is already exist. It does not support iteration like loop statements and conditional statements like If-Else.It is built on the concept of mathematical functions which uses conditional expressions and recursion to do perform the calculation.Functional programming Decompose the problem into ‘functions.Functional programming method focuses on results, not the process.Object-oriented ProgrammingĬharacteristics of Functional Programming
Basic Functional Programming Terminology and Concepts.Characteristics of functional Programming.Therefore, unlike other procedures which depend on a local or global state, value output in FP depends only on the arguments passed to the function. It avoid concepts of shared state, mutable data observed in Object Oriented Programming.įunctional langauges empazies on expressions and declarations rather than execution of statements. Functional programming (also called FP) is a way of thinking about software construction by creating pure functions.
