Template Literals

A tagged template is a more advanced form of template literals where you prefix a template literal with a function name (the 'tag'). This function receives the template's processed string parts and expressions as arguments, allowing you to customize how the template is processed and what is returned. The tag function's first argument is an array of string literals, and the remaining arguments are the evaluated values of the template's expressions. This powerful feature enables custom string parsing, sanitization, localization, styling (like with styled-components in React), and even building domain-specific languages. Unlike regular template literals that always result in strings, tagged templates can return any data type.
