What are the pros and cons of functional programming vs object-oriented programming?

Functional programming and object-oriented programming are two popular paradigms in JavaScript. Both have their own advantages and disadvantages.

Functional programming is a programming paradigm that emphasizes on the use of functions to solve problems. It is based on the concept of pure functions, which means that a function should always return the same output for a given input and should not have any side effects. The main advantage of functional programming is that it makes code more predictable and easier to test. It also promotes code reuse and modularity. However, functional programming can be difficult to learn for developers who are used to imperative programming.

On the other hand, object-oriented programming is a programming paradigm that focuses on the use of objects to solve problems. It is based on the concept of encapsulation, inheritance, and polymorphism. The main advantage of object-oriented programming is that it makes code more organized and easier to maintain. It also promotes code reuse and modularity. However, object-oriented programming can be more complex and harder to learn for beginners.

In conclusion, both functional programming and object-oriented programming have their own advantages and disadvantages. The choice between the two depends on the specific requirements of the project and the skills of the development team.
