This example demonstrates a simple utility function that formats a person's name by combining a first and last name with a space. It shows how to use TypeScript's type annotations and template literal syntax to create a readable, reusable function. The code defines `formatName`, which takes two string parameters and returns a single formatted string using the `${}` template literal syntax. It is a straightforward illustration of basic string manipulation and function export in a TypeScript module, suitable for use in web applications or Node.js projects.
