JavaScript Getters and Setters

-

JavaScript has properties with getters and setters, just like languages such as C#. They don't seem to be as widely used. If you're defining an object and want to handle events, validate input, format output, etc., then properties are a good way to make that happen. Or you could also use Java-style getX/setX methods, which accomplish the same thing with a different syntax.

DotNet CLI

Don't be afraid of using the .NET CLI and skipping Visual Studio. Visual Studio Code is a fantastic IDE for .NET projects - obviously not as powerful as Visual Studio, but it's significantly lighter and faster, and the integrated terminal is desperately needed in Visual Studio. The .NET CLI is actually incredibly easy to work with. This video shows some of the basic commands. See the documentation for more. View code on GitHub

Nullable reference types

C# now includes the concept of a "nullable" reference type. The name is a bit confusing, because reference type variables were always nullable. What they really should have called it is "non-nullable", since that's what's different now. In the past, you could declare a string variable or property, and it was perfectly valid to assign that to null. So if you're going to use it, you need to do a null-check to avoid exceptions. Now, if you turn on the flag in your project, the compiler will help you avoid null exceptions, by forcing you to define when a variable or property is allowed to be null, and there are warnings or errors to alert you when you're trying to potentially set a non-nullable variable to null.

Static constructors in C# are a bit tricky to use. Static classes and methods go against OOP principals in the first place, so their use should be limited to only where they make sense. Here are some basic behaviors about static constructors: View code on GitHub
