How do you apply web development standards to different paradigms?

1 Procedural paradigm

The procedural paradigm is one of the oldest and simplest paradigms in web development, which involves writing a series of instructions that are executed sequentially. Examples of procedural languages include PHP, C, and Python. To ensure your code meets web development standards when using the procedural paradigm, it is important to use descriptive and consistent naming conventions for variables, functions, and files. Additionally, code should be organized into modular and reusable functions that perform a single task. Comments should be added to explain the logic and purpose of each procedure, while indentation, spacing, and brackets should be used to make the code readable and maintainable. Lastly, user input should be validated and sanitized to prevent errors and security issues.

3 Functional paradigm

The functional paradigm is based on functions, which are pure and stateless expressions that return a value. Functions can be composed, nested, and passed as arguments to other functions. Examples of functional languages include Haskell, Lisp, and JavaScript. To apply web development standards to the functional paradigm, you should use immutable data structures and avoid side effects that modify the program or environment. Additionally, you should use higher-order functions and lambda expressions to create concise code, as well as recursion and iteration to manipulate data and perform calculations. Pattern matching and destructuring can be used to handle different cases and extract values from data structures. Finally, functional programming libraries and frameworks can be used to simplify common tasks and leverage existing functionality.

4 Reactive paradigm

The reactive paradigm is based on the concept of streams, which are sequences of events that occur over time. To apply web development standards to the reactive paradigm, you should use observables and operators to create and manipulate streams of data and events, subscribers and callbacks to react to changes in streams and perform actions, schedulers and promises to manage concurrency and asynchronous operations, components and hooks to create reusable and stateful user interface elements that update automatically when streams change, as well as testing and debugging tools to monitor and troubleshoot streams and their behavior. RxJS, React, and Angular are some examples of reactive languages and frameworks.
