Classes & Functions - Which is better?

Being asked whether I prefer classes to functions is a setup question, as it’s quite difficult to determine without a use case. Why? Well, classes and functions are two fundamental building blocks used to develop software. A class is a blueprint for creating objects that have specific properties and behaviors. It is a template that defines the structure of an object, and how it behaves. Functions, on the other hand, are reusable blocks of code that perform a specific task. They can take input, perform operations on that input, and return output.

The decision to use classes or functions simply depends on the specific needs of a project. Generally, classes are useful for creating complex data structures, such as trees or graphs, or for modeling real-world entities, such as cars or buildings. For example, suppose you were creating a program that needs to model a car. You could create a car class that defines properties like make, model, and year, as well as methods like start and stop. This would allow you to create car objects that have specific properties and behaviors.

Functions, on the other hand, are often used to perform tasks or operations, such as sorting or filtering data. For example, suppose you are creating a program that needs to model a car. You could create a car class that defines properties like make, model, and year, as well as methods like start and stop. This would allow you to create car objects that have specific properties and behaviors.

Without getting too much into object-oriented programming vs functional programming, one advantage of using classes is that they allow for inheritance, which is a key feature of object-oriented programming. Inheritance allows a subclass to inherit properties and methods from its parent class, which can save time and reduce code duplication. Additionally, classes can help to organize code into logical structures, which can make it easier to understand and maintain over time.

Functions, on the other hand, are typically simpler and faster than classes. Because they are focused on performing a specific task, they can be optimized for performance in a way that classes cannot. This can be important in situations where speed and efficiency are critical, such as in high-traffic web applications.

Really, at the end of the day, both classes and functions are important concepts when developing, and each has its own strengths and weaknesses. Classes are useful for creating complex data structures and modeling real-world entities, while functions are often used to perform tasks and operations. Just keep in mind that when choosing between classes and functions, it's important to consider the specific needs of the project at hand and to choose the approach that best fits those needs.

Hope this helps you! Happy developing!
