What is Literal Types?
Literal types are a feature that allows you to specify the exact value a variable can hold. Instead of just saying a variable is a string or a number, you can specify that it can only be a particular string like "hello" or a particular number like 42. This enables more precise type checking and helps catch errors at compile time by ensuring that variables only hold the intended values.
