In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes. In the client–server model, the client is usually considered the frontend, handling user-facing tasks, and the server is the backend, managing data and logic.
Logic programming is a programming, database and knowledge representation paradigm based on formal logic. A logic program is a set of sentences in logical form, representing knowledge about some problem domain. Computation is performed by applying logical reasoning to that knowledge, to solve problems in the domain.
Functional logic programming is the combination, in a single programming language, of the paradigms of functional programming and logic programming. [1] This style of programming is embodied by various programming languages, including Curry and Mercury. [2] [1] A more recent example is Verse. [3]
When a web page is loaded, the browser creates a Document Object Model of the page, which is an object oriented representation of an HTML document that acts as an interface between JavaScript and the document itself. This allows the creation of dynamic web pages, [13] because within a page JavaScript can:
Logical Cohesion: A module has logical cohesion if it has available a series of functions, but only one of them is executed. For example, function perform_arithmetic( perform_addition, a, b ). Temporal Cohesion: A module has temporal cohesion if it performs functions related to time. One example, function initialize_variables_and_open_files().

Prolog (1972) stands for "PROgramming in LOGic." It was developed for natural language question answering, [12] using SL resolution [13] both to deduce answers to queries and to parse and generate natural language sentences. The building blocks of a Prolog program are facts and rules. Here is a simple example:
