JavaScript Class Privacy — Or Lack ThereofClasses are nothing new in programming, but their implementation in JavaScript is, well, weird. For anyone used to classes in other languages, you might think of them as blueprints from which new instances are copied. Additionally, you might think that these classes would offer public, private, and protected instance properties. In JavaScript, neither of these is true: new instances of objects have a prototypal inheritance relationship with their parents and there is no such thing as private or protected properties. In this article, I am going to dive into the latter point a bit further.Note: If you enjoy this article, please give it a clap ?

In most traditional programming languages code reuse typically comes in the form of inheritance. I’ve been on many projects where the innocent BaseThingy quickly turns into DoesEveryThingy in just a few short months because unfortunately inheritance wasn’t meant for code reuse in ways we often hope for. You see, well designed systems are often constructed from smaller objects that do one thing well and leave everything else to others. The problem is sometimes we have classes that require management of other smaller objects, we can call these classes Controllers as their job is to control other classes. It can be tempting to create a BaseController which will handle things like thread pool management, instantiating different views, injecting models, etc. The downside to this approach (...)
