Template Literal Types

Template literal types in TypeScript are a way to manipulate string values as types. They allow you to create a type based on the result of string manipulation or concatenation. Template literal types are created using the backtick (“) character and string manipulation expressions within the type.

For example, the following is a template literal type that concatenates two strings:

type Name = `Mr. ` + string;

let name: Name = `Mr. Smith`;  // ok
let name: Name = `Mrs. Smith`;  // error

In this example, the Name template literal type is created by concatenating the string "Mr. " with the type string. This type can then be used to enforce that a value must be a string that starts with "Mr. ".
