define n in template string code example

Example 1: string interpolation javascript

const age = 3
console.log(`I'm ${age} years old!`)

Example 2: javascript template literals

//Must use backticks, `, in order to work.

let a = 5;
let b = 10;
console.log(`Fifteen is ${a + b} and
not ${2 * a + b}.`);

//Output:
//Fifteen is 15 and not 20.
