Chapter 7. Functional and Object-oriented Programming in JavaScript
You will often hear that JavaScript is a blank language, where blank is either object-oriented, functional, or general-purpose. This book has focused on JavaScript as a functional language and has gone to great lengths to prove that it is. But the truth is that JavaScript is a general-purpose language, meaning it's fully capable of multiple programming styles. Like Python and F#, JavaScript is multi-paradigm. But unlike those languages, JavaScript's OOP side is prototype-based while most other general-purpose languages are class-based.
In this final chapter, we will relate both functional and object-oriented programming to JavaScript, and see how the two paradigms can complement each other and coexist side-by-side. In this chapter the following topics will be covered:
- How can JavaScript be both functional and OOP?
- JavaScript's OOP – using prototypes
- How to mix functional and OOP in JavaScript...
