What are some practical examples of TypeScript types?

Can you give me some practical examples of TypeScript types?

Sure! TypeScript has several built-in types like 'string', 'number', and 'boolean'. For example, you can define a variable like this: let age: number = 30;.

What about more complex types?

Great question! You can create complex types using interfaces and types. For instance, you can define an interface for a user: interface User { name: string; age: number; }.

How do I use union types?

Union types allow a variable to hold multiple types. For example: let id: string | number; means 'id' can be either a string or a number.

Can you explain type assertions?

Absolutely! Type assertions let you override TypeScript's inferred type. For example: let someValue: any = 'this is a string'; let strLength: number = (someValue as string).length;.
