[JS] Backtick String

Below multiple liens of strings with “” are not correct syntax in JS.

Use of backtick `` will allow you to combine strings

let originList = "Guests:
* John
* Pete
* Mary
";

But you can use it with backticks

let guestList = `Guests:
 * John
 * Pete
 * Mary
`;
console.log(guestList);

This is usuful when you declare HTML syntax as a string.

// provide better human readable
const html = `
  <div>
    <p>Example</p>
  </div>
`;
console.log(html);

Using ${} will allow to use single line JS syntax and excute.

function sum(a, b) {
  return a + b;
}

console.log(`1 + 2 = ${sum(1, 2)}`);

// Result
// 1 + 2 = 3
