What are advanced type assertions in TypeScript?

Advanced type assertions in TypeScript allow you to override the compiler's inferred type. You can use them to specify a more specific type when you know more about the value than TypeScript does.

Can you give me an example of how to use type assertions?

Sure! For instance, if you have a variable someValue that you know is a string, you can assert its type like this: let strValue = someValue as string;.

Are there any risks associated with using type assertions?

Yes, using type assertions can lead to runtime errors if you're not careful. If you assert a type incorrectly, it can cause your code to behave unexpectedly.

When should I use type assertions instead of type guards?

Type assertions should be used when you are certain about the type of a variable, while type guards are better for runtime checks to ensure type safety.
