Functional vs Object-Oriented Programming

The article explains that programming paradigms are ways of organizing code to implement solutions, and it focuses on functional programming and object-oriented programming in JavaScript. It describes functional programs as sequences of stateless function evaluations and OOP programs as sets of interacting objects.

It then shows the same simple form example in both styles. In the functional version, one function performs the calculation and another displays the result. In the OOP version, a class stores the form and input fields and binds a submit handler that prevents the default event and logs the sum. The conclusion says these paradigms are only two of many ways to structure code, and that real-world work often mixes both depending on the problem.

Reading notes

#

• Programming paradigms are approaches for organizing code to implement solutions.
• The article focuses on functional programming and object-oriented programming in JavaScript.
• Functional programming is described as treating programs as sequences of stateless function evaluations.
• Object-oriented programming is described as treating programs as sets of interacting objects.
• The example uses a simple form that calculates the sum of two numbers.
• In the functional approach, one function calculates the sum and another prints the result.
• In the OOP approach, a class stores the form and inputs and registers a submit handler.
• The article says understanding both approaches can increase flexibility in problem-solving.
• It says developers usually combine the two paradigms depending on the problem.
