Tagged template literals

function getPersonInfo(one, two, three) {

const person = 'Lydia';
const age = 21;

getPersonInfo`${person} is ${age} years old`;

If you use tagged template literals, the value of the first argument is always an array of the string values. The remaining arguments get the values of the passed expressions!
