JavaScript string interpolation

In JavaScript (ES6 and later), we can use string interpolation when we want to concatenate strings with variables in a neater arrangement...

Instead of using plus (+) signs and a bunch of quotation marks:

var x = 'something'
var y = 'another thing'
var z = 'yet another thing'

var sentence = 'We would like' + x + 'and then' + y + 'and also' + z + '!';

We could use a different syntax:

const x = 'something'
const y = 'another thing'
const z = 'yet another thing'

const sentence = `We would like ${x} and then ${y} and also ${z}!`

Note that:

• we use backtick symbols (`) to encapsulate the total string
• we use { curly braces } around the variable names
