What are the benefits of using optional properties in programming?

Optional properties allow developers to create more flexible and maintainable code. They enable you to define objects without requiring all properties to be present, which can simplify data handling.

Can you give me an example of how optional properties work?

Sure! In TypeScript, you can define an interface with optional properties like this: interface User { name: string; age?: number; }. Here, age is optional.

What are the potential downsides of using optional properties?

One downside is that it can lead to more complex code, as you need to handle cases where the optional properties are undefined. This can increase the risk of runtime errors if not managed properly.

How do optional properties affect code readability?

Optional properties can enhance readability by making it clear which properties are essential and which are not. However, if overused, they can also make the code harder to understand.
