What is type alias?  A type alias allows you to provide a new name for an existing data type into your program. Type alias does not create new types they simply provide a new name to an existing type. The main purpose of type alias is to make our code more readable.     Example: typealias Name = String let firstName:Name = "Pawan" Thanks for reading, Happy Coding 👨‍💻
