## JavaScript: Tips of the Day

JavaScript: Tagged template literals

```function getPersonInfo(one, two, three) {
console.log(one);
console.log(two);
console.log(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!
