I'm trying to wrap my head around some code written by someone who's no longer around, and I've noticed there are several classes in a module that includes various functions. I'm aware this is a fundamental programming concept, but I would really appreciate a clearer explanation of what classes do, how they're generally used, and any tips for beginners like me who are self-taught.

Absolutely! Classes let you define a collection of related properties and methods that all pertain to a particular object. For instance, in PowerShell, classes can seem less rigid and sometimes are more like loose guidelines for defining your objects. While they have a lot to offer, especially for organization, you don't necessarily need to use them if you're more comfortable with functions and simple data structures. It all depends on the complexity and needs of your project!
Classes in PowerShell are kind of a mixed bag. They’re not always necessary, especially for simpler tasks, since you can often achieve what you need with functions or PSCustomObjects. But they can provide enhanced structure for larger projects, allowing for better organization and flexibility. They may introduce new complexities, so weigh the benefits!
Classes can be thought of as blueprints for creating objects. They allow you to define both properties (like 'Manufacturer' or 'ScreenSize' for a 'Phone' class) and methods (like 'PowerOn' or 'DialNumber'), helping you to keep related data and functions organized together. This makes your code neater and easier to manage. In essence, they help encapsulate data with the functions that operate on that data, making your programs more structured.
That's a good point! Sometimes, trying to force classes into simple scripts can lead to overcomplication. Balancing between classes and functions is key.
