What are the benefits of using union types in TypeScript?

What are the benefits of using union types in TypeScript?

Union types allow you to define a variable that can hold multiple types, enhancing flexibility and type safety.

Can you give me an example of how to use union types?

Sure! You can define a variable like this: let value: string | number; This means value can be either a string or a number.

What happens if I try to assign a different type?

If you assign a type that is not included in the union, TypeScript will throw a compilation error, helping you catch issues early.

Are there any downsides to using union types?

One downside is that it can make your code more complex, especially if overused, leading to harder-to-read code.
