Answer
Tagged templates in JavaScript allow you to parse template literals with a function. The function receives the literal strings and the values as arguments, enabling custom processing of the template. For example:
js
function tag(strings, ...values) {
return strings[0] + values[0] + strings[1] + values[1] + strings[2];
}
const result = tag`Hello ${"world"}! How are ${"you"}?`;
console.log(result); // "Hello world! How are you?"
