For example, a computer programmer might use a function to count the number of guests in the room. However, if they were to do this without any other “pure” functions, they would be performing a sub-optimal application of the function and could end up with a less efficient program than one that had the use of pure functions.
Functional programming is also used as a technique to implement algorithms into computer programs. For instance, instead of using a loop to iterate over the items in an array, a functional programmer may decide to write a series of computations in the form of an algorithm and then apply the algorithm to each item in the array.
Functional programming can also be used as a technique for data structures. For example, instead of using arrays to store objects, an object-oriented programmer might choose to use a List or Set instead of an array.
Some examples of the concepts of Functional Programming can be found in computer textbooks. Although the term Functional Programming is not commonly used, it is a fundamental concept of computer programming that many programmers will use.
Computer programmers need to learn how to implement various forms of functional programming if they wish to write computer programs that are more efficient. By practicing Functional Programming, programmers will be able to identify which types of program are optimized for certain problems.
One of the benefits of Functional Programming is that it can provide an easy way for programmers to introduce new ideas into their programs. For example, programmers who want to develop an application that is both visually attractive and efficient at sorting large amounts of data will have an easier time writing a Functional Programming program than an OO program.
By using Functional Programming, programmers will be able to develop programs that can better optimize their programs. Functional programming techniques should therefore be used in conjunction with traditional programming techniques, including object oriented programming.
The concepts of Functional Programming are based on the following concepts. These concepts include:
First, Functional Programming is based on the belief, “Functions should be defined before they are used.” Therefore, before a programmer can begin writing a functional program, they need to first understand the types of functions they can use to define a program. After understanding these types of functions, the programmer will be able to write programs using only those functions that they know.
Second, Functional Programming is based on the belief, “The simplest program is the best.” In other words, a program that uses the most basic functions is better because that a program that uses the least amount of functions. Functional programs are also usually the most efficient.
Third, Functional Programming is based on the concept, “The programmer should have a language in mind which helps him to define functions.” A programmer should be able to write a program in such a way that he will be able to define these types of functions. A programmer will not be able to write a functional program if he cannot write code which is easy to read and understand.
Fourth, Functional Programming is based on the concept that a Functional Programmer should have a language that is easy to implement. By using a programming language that is easy to read and understand, the programmer can create a functional program that is easy to implement.
