Type Aliases

What is Type Aliases?
Type aliases in TypeScript create a new name for an existing type. This new name can then be used anywhere you would normally use the original type. They don't create a new type; instead, they offer a more readable and convenient way to refer to potentially complex or frequently used types, such as unions, intersections, or tuple types.
