What are the differences in handling optional properties across programming languages?

What are the differences in handling optional properties across programming languages?

Different programming languages have various ways to handle optional properties. For example, in TypeScript, you can define optional properties using a question mark (e.g., propertyName?: type). In contrast, Python uses default values or the None type to indicate optional parameters.

Can you give examples of how JavaScript and C# handle optional properties?

Sure! In JavaScript, you can use the spread operator or default parameters to handle optional properties. In C#, you can use nullable types or method overloading to achieve similar functionality.

What about languages like Ruby or Go?

In Ruby, optional parameters can be defined with default values, while in Go, you typically use variadic functions or struct types to handle optional fields.

Are there any languages that don't support optional properties?

Yes, some languages like C do not have built-in support for optional properties, and you would need to implement similar functionality manually.
