Logic programming can be used for research and testing complex theorems - it is also closely connected to development of machine learning and artificial intelligence. Key benefits include flexibility and minimalist syntax. However, it can be confusing if the logical rules are not expressed well. Examples: Prolog, Datalog, Mercury.
As the name suggests, this paradigm is based on the execution of a series of mathematical functions, which form the building blocks of the program and perform all manner of tasks. These languages avoid flow controls like loops and instead favor recursive functions. This paradigm reduces code complexity and can be used to solve complex problems. However, it can be difficult to learn and tricky to scale for larger projects. As with the logic paradigm, some functional programming languages can also support imperative style programming if required.
Examples: JavaScript, Haskell, Scala. It all depends on what you need to do, what resources you have available, and who else is working on the project. Most important is finding a skilled and experienced programmer that knows when to use the different paradigms to maximize the benefits of each.

Some are clearly suited for Objected Oriented programming. Others get simpler when you use constraint solving or pattern matching. Let us go on a whirlwind tour of 4 different programming paradigms — Procedural, Object-Oriented, Functional and Logical. This article will give you a better understanding of the various programming paradigms. Procedural programming can also be referred to as imperative programming.
It is a programming paradigm based upon the concept of procedure calls, in which statements are structured into procedures also known as subroutines or functions. They are a list of instructions to tell the computer what to do step by step, Procedural programming languages are known as top-down languages. Most of the early programming languages are all procedural.
Logical programming is a computer programming paradigm that has its foundations in mathematical logic in which program statements express facts and rules about problems within a system. Rules are written as logical clauses with a head and a body.
They also follow a declarative rather than an imperative approach. However, what does that mean? So rather than providing a step by step instruction imperative , you tell the system what you need and let it try to come up with a solution declarative.
Prolog follows the Logical paradigm and is probably the most famous language in the logical programming family. Prolog, like SQL, has two main aspects, one to express the data and another to query it. The basic constructs of logical programming, terms, and statements, are inherited from logic.
There are three basic statements:. Functional programming is a programming paradigm where you have a style of building the structure and elements of computer programs. Here you treat computation as an evaluation of mathematical functions and you avoid changing-state and mutable data. Functional programming consists only of PURE functions. So, what do you understand by Pure functions? Pure functions are those which take an argument list as an input and whose output is a return value.
Now you may feel that all functions are pure as any function takes in values and returns a value. And in such cases, the return value of that function is not entirely dependent on the list of arguments received as input and can also have side effects.
So, what do you understand by the term side effect? A side effect is a change in the state of an application that is observable outside the called function other than its return value.
For example: Modifying any external variable or object property such as a global variable, or a variable in the parent function scope chain. Skip to content. Change Language. Related Articles. Table of Contents. Save Article. Improve Article. Like Article. String name;. String emailid;.
