When should I use union types or optional types in TypeScript?

Can you explain when to use union types versus optional types in TypeScript?

Sure! Union types allow a variable to hold multiple types, while optional types indicate that a variable may or may not be present.

Can you give me an example of each?

Of course! For union types, you might have let value: string | number;. For optional types, you could use let name?: string;.

What are the benefits of using union types?

Union types provide flexibility, allowing you to handle multiple data types in a single variable, which can simplify your code.

And what about optional types? Why would I use them?

Optional types are great for defining properties that may not always be present, making your code more robust and easier to manage.
