  <h2>Principles of Object-Oriented Programming Languages</h2>
  <p>Object-Oriented Programming (OOP) languages are based on several key principles that help developers create efficient and maintainable code. These principles include:</p>
  
  <h3>1. Encapsulation</h3>
  <p>Encapsulation is the concept of bundling data and methods that operate on that data into a single unit, known as an object. This helps in hiding the internal state of an object and only exposing the necessary functionality to the outside world.</p>
  
  <h3>2. Inheritance</h3>
  <p>Inheritance allows a class to inherit properties and behavior from another class. This promotes code reusability and helps in creating a hierarchy of classes with shared characteristics.</p>
  
  <h3>3. Polymorphism</h3>
  <p>Polymorphism allows objects of different classes to be treated as objects of a common superclass. This enables flexibility in code design and allows for more dynamic and flexible behavior.</p>
  
  <h3>4. Abstraction</h3>
  <p>Abstraction involves hiding the complex implementation details of an object and only showing the necessary features to the user. This helps in simplifying the code and making it easier to understand and maintain.</p>
</div>

Principles in coding languages refer to the fundamental concepts and rules that govern how a programming language is structured and used.

Object-Oriented Programming Languages are a type of coding language that follows the principles of encapsulation, inheritance, polymorphism, and abstraction. Examples of Object-Oriented Programming Languages include Java, C++, and Python. These languages are widely used in various applications such as system programming, web development, data analysis, and artificial intelligence due to their ability to create modular and reusable code.

First-class and Higher-order Functions are key concepts in functional programming languages, where functions are treated as first-class citizens and can be passed as arguments to other functions or returned as values. First-class functions can be assigned to variables, stored in data structures, and passed around just like any other value. Higher-order functions, on the other hand, take one or more functions as arguments or return a function as a result, allowing for powerful abstractions and concise code in languages like Haskell, Erlang, and Clojure.

Pure Functions are a fundamental concept in functional programming languages, where they always produce the same output for a given input and have no side effects. This means they do not modify any external state or variables, making them predictable and easier to test. Pure Functions promote immutability and help in writing more maintainable and scalable code.

Immutability in coding languages refers to the concept of data that cannot be changed once it has been created. This property is important in programming as it helps prevent unintended side effects and makes code easier to reason about. Immutability is commonly found in functional programming languages like Haskell, Erlang, and Clojure, where data is treated as immutable by default.

Recursion is a programming technique where a function calls itself in order to solve a problem. It is a powerful tool used in various programming languages for tasks that can be broken down into smaller, similar subproblems. Recursion allows for elegant and concise solutions to complex problems, but it can also lead to stack overflow errors if not implemented correctly.

Haskell is a functional programming language known for its strong static typing and lazy evaluation. It is used in a variety of applications such as system programming, web development, data analysis, and artificial intelligence. Haskell's syntax and semantics focus on immutability, pure functions, and higher-order functions, making it a powerful tool for building complex and efficient programs.

Erlang is a functional programming language that was developed in the 1980s for telecommunication systems. It is known for its concurrency and fault-tolerance features, making it ideal for building distributed and real-time systems. Erlang's syntax is similar to Prolog, and it is used in applications such as system programming, web development, and telecommunications.

Clojure is a functional programming language that runs on the Java Virtual Machine (JVM) and is designed for concurrency and immutability. It is known for its simple syntax, powerful data structures, and emphasis on functional programming principles. Clojure is commonly used for web development, data analysis, and artificial intelligence applications.

<div>
  <h2>Functional Programming Languages</h2>

  <ul>
    <li><strong>Immutability:</strong> Functional programming languages emphasize immutability, meaning that once a variable is assigned a value, it cannot be changed.</li>
    <li><strong>Higher-order functions:</strong> Functions in functional programming languages can take other functions as arguments or return functions as results.</li>
    <li><strong>Recursion:</strong> Recursion is commonly used in functional programming languages to solve problems by breaking them down into smaller, simpler problems.</li>
    <li><strong>Referential transparency:</strong> In functional programming languages, functions always return the same output for the same input, making them predictable and easier to reason about.</li>
    <li><strong>Lazy evaluation:</strong> Some functional programming languages use lazy evaluation, which means that expressions are not evaluated until their results are actually needed.</li>
  </ul>
  <p>Some popular functional programming languages include Haskell, Lisp, Clojure, and Erlang. These languages are often used in academic and research settings, as well as in industries where correctness and reliability are crucial, such as finance and healthcare.</p>
